Hey Jason. I am also named Jason. I, however am not 7 days into e-cigs. I have heard of them before, even had a run-in or two with people
vaping, but that was about it. Until 5 days ago when a co-worker (non-smoker who was constantly on my case) gave me a disposable one and pretty much forced me to try it. I liked it. A LOT. I mean I'm no dummy and knew a pack a day habit was slowly killing me, but I was addicted. I never REALLY tried to quit, maybe claimed to once or twice when I couldn't afford 6 or 7 bucks for a pack. Anyways. I went
through that first disposable pretty quick, like 8 hours. I picked another at the gas station near my house for $9. This seemed expensive. I thought $9 every 8 hours vs $6 a day.
Indeed. Those things can work if you use them sparingly like traditional NRT, but the accepted NRT products used as advertised have a _very_ low success rate. The price is perhaps a little less than tradition NRT, but they are not accepted as such in most countries, even the ones that allow them to be sold over the counter with nicotine in them.
So I talked to a friend about it and he told me about Blu kits you could buy at Walgreens. That became my next stop. I picked up a kit with a two part design you could recharge and replace. Wow did I think these were awesome. All this was before I decided to research e-cigs for their health risks/benefits.
Yes, you're on the normal progression for a vaper. Most of us start this way and progress rapidly to ego style batteries which have more options for vaporisers such as clearomisers and cartotanks. You can research these things on here but ask questions if you need to.
The next step is variable voltage ego batteries like the the Ego-C Twist and the Spinner. These allow you to dial the voltage up or down to give the best vaping experience. As you progress through the non-smoking phase of vaping it's vital to have a device that you find satisfies your cravings. I think most of us use the aquisition of new toys and flavoured juices and learning how it all works as a distraction as well. It all helps.
So when I did I became absolutely amazed. I had no idea what I was getting myself into. I became almost overwhelmed. I quickly learned that the majority opinion is e-cigs can't possibly be as bad as tobacco smoking. But it was the ways to vape(?) that blew my mind. This is why I'm here.
Yes, you will find your lungs clearing and you may cough up nasty stuff in the morning - evidence of your lungs clearing. After a few days the carbon monoxide will be out of your system so you may be able to walk further and enjoy exercise more. After a few week to a month you may notice that your sense of taste and smell are getting MUCH better. You may smell or taste things in way that you haven't experienced since your childhood (some smells, especially food, can trigger memories that may surprise you).
Where should I go from here. I've read that vaping(?) is supposed to be cheaper, but I ask how when all I see are starter kits costing $40 to $100+.
Maybe forget the starter kits unless they contain exactly what you are looking for, but still do some research in case you can buy the separate components elsewhere for less, which is normally the case. Anything that only takes cartridges has a higher running cost and/or requires a lot more fiddling so you might want to look at some Ego style batteries.
Have a look at the twist and spinner batteries, which are cheap and have VV (variable voltage). Even if you progress past the the Ego-C twist stage, these devices are still useful because they are lighter and smaller. I always have one with a Vivi Nova mini clearomiser in my top pocket while at work. You should google all of these things.
Then I see hi-tech devices with crazy pieces and parts that I don't understand (yet) costing way more. E-liquid, clearomizers, etc.
Anyways help me!?
You may want to investigate clearomisers like the CE3, CE5, Vivi Nova (mini), Kanger etc. Take your time. These devices are not terribly expensive, and you really can't have too many. (well you can, but that would be hoarding

Many of us try nearly all of them before we settle on ones that work best for us. Buy only ones or twos at the most until you find out what works for you.
You don't really need to investigate mods at this stage, but if you do the common ones you will hear about here are things like the Provari, Lavatube, Vamo V2 (my own personal device while at home or kicking back and the cheapest mod listed here with both vv and vw), eVic and I don't know what else. Keep reading but if you want some serious vaping capability, start having a look at the Ego-C twist or spinner as a couple of these devices will never go to waste, either as backup for a mod or as your carry around vape at work.
Yes, you do spend a little on harware at this stage. I could have saved money if I'd just bought my current setup straight off the bat: Two Ego-C twist batteries, and a Vamo V2. I have no wish to aquire more batteries or mods at this time - my search is over. It took me about three weeks to get here though. I also started DIY juices, but most of us just buy juice to start with as both this and rebuilding coils for your atomiser heads are more advanced topics.
I can say that my actual running costs now that the hardware aquisition is over is somewhere in the order of $2.80 per week with all the DIY stuff I am doing including rebuilding the coils for my vivi novas. If I had to buy everything my spend on juice and clearo heads (ie atomiser heads) would proably be in the order of $17-$20 per week. If I stayed on a cigalike system and had to buy cartridges for it (ie the Blu or similar) then my running costs might be nearly what I was spending on cigarettes.
Somewhere inbetween, you should find your happy medium but if you're handy with things then there's no reason why you can't get the cost down to what I have in a few weeks. Just expect to spend a bit and make a few wrong turns along the way.
