Welcome and congratulations on your decision to quit smoking.
When I first began my priorities were getting the nicotine I needed to curb my craving for a cigarette. Next was finances. I only had 60.00 to spend on this endeavor. Another priority was getting the best I could for that small investment. Last of all was the safety of vaping and the need to truly feel as if I'd benefited health wise from switching. Safety was my last priority since common sense told me it was at least as safe as smoking.
Nicotine - A little over two months into this I've found that 18mg more than satisfies my nicotine needs as a former PAD smoker. 24mg was WAY too much for me and 12mg not enough... I was constantly vaping. Lesson learned is that I should go slowly in reducing my nicotine level so that I don't reach for a cigarette. I haven't had one since the day I started vaping. I feel now that I may be able to go to 12mg as the amount of liquid I vape in a day is decreasing.
Price/Quality product - After much research I decided that a 30w Istick and Nautilus Mini were the best pieces of equipment for me as a new vaper. Reasons were ease of use, relatively problem free, quality name brands/good reviews and ability to use more advanced tanks (sub ohm) in the future. So, off to my local B&M I went, hopefully to pick up these items. Well, when I got there I was very disappointed to find that my 60.00 wouldn't touch that equipment (54.95 for the Istick and 34.99 for the Nautilus). Back to the internet to search for something cheaper. Fortunately for me (and my wallet) I was able to find these things much cheaper online. I got the Istick for 19.99 and the Nautilus for 18.99. Big lesson learned is that the local vape shops charge a LOT more for this stuff than online vendors. And, this set up is as good as everyone said it would be. I haven't had any problems whatsoever with it.
Safety - Ok, at first I was sad to see all the talk of dangers of vaping. I thought "What's the point?" But, determined, I sought out credible sources for my information and slowly began to realize that much of the hype on the dangers of vaping were just that. Propaganda used against the vaping community. Nonetheless, I did come across some information that worried me and that is the concerns some have over ingredients in some flavors. That's when I found out that I do have the option to just vape unflavored, PG/VG and nicotine only. Many said that it tastes fine to them and some even preferred it. Being that my first priority was getting nicotine into my system I decided that this would do for me. So, with the last 20 dollars I had to spend, I ordered enough PG, VG, and nicotine to make 300ml of unflavored juice. I got it, mixed it and it was great just as many have said. I've never even vaped a flavor yet. (can't miss what you never had) Lesson learned is that I can get 10 times (or more if bigger quantities are ordered) the amount of unflavored juice for the same price some charge for flavored. I don't have to worry about what unsafe ingredients might be in the liquid. And, I haven't had to buy a coil yet for my tank. Cheap, cheap, cheap.
So, that's how I got started with only 60.00 and I got everything I need to vape for a good while. I only use around 3ml a day so my juice should last at least 3 months. I do realize that flavors are what keep many from going back to cigarettes and most flavors aren't known to have the ingredients that may cause harm so that's probably what you will want. As for me, I'm happy with what I have now and am saving for a subtank and some wonderful flavor to use in it for a treat at times. A friend of my son is addicted to Churro flavor... loves it so that may be the first flavor I try (or Root beer, lol). Good luck with everything and remember that every cigarette you don't smoke is what matters, not those you do.
