Maniacal - if you're talking about the kit posted, yeah that's a basic Ego starter that you'll find in a lot of places...I paid $25 for just one battery and one clearomizer (the thing that screws onto the battery and holds the juice), so this is a killer price - but since it ships from China it takes a couple weeks. I have two of these kits on order myself (they have lots of other color choices too) as backups for me and the wife.
The reason I recommended that kit is because it has the Evod clearomizers attached to the batteries (the ones with the solid color and a little window to see the juice level, rather than other totally clear ones). I like them a lot because they're cheap and easy to see the juice levels inside - it's nice to keep a few of them around in case you have a problem with one or if, like me, you like to have a few different flavors of juice to switch up.
I would say it's a good idea to order juices now, as others have recommended - you're going to need them to use your e-cig when it shows up.
The difference between the regular batteries and the twist is the little twisty thing on the bottom of the battery, like this:
Joyetech Ego Twist
That will let you turn the power up or down to find the best level to vaporize your juices - some burn with too much power, others don't have much flavor with too little. A regular battery starts around 4.2v when charged, spends most of its life around 3.7v, and can fall as low as 3.2v when it's almost dead and needs a recharge. Again, it works for me (because I have a backup battery charged to switch to if it gets weak), but others swear by the adjustable voltage.
Back to those Evod clearomizers and the clearomizer/cartomizer debate - the coil head/atomizer (burner) is a little piece that screws into the bottom cap on the Evod, I've only replaced one of them and I've been using my Evods (granted, I spread my use across 3 tanks) for 3 weeks solid now. Most of the time you can clean them up by running under hot water and drying them out if they get gunked up, I do that every 3-4 tanks of juice or whenever I change flavors. They're cheap, and if you end up doing a Fasttech order I'd pick up 5 or so of them:
$1.28 EVOD Electronic Cigarettes Atomizer Heating Core - 2.4
Even if I was replacing a head with every single juice fill-up, it would cost me about $1.50 per tank including the juice, and 2 of those a day would beat the heck out of spending $6 a day on smokes. And that's a ridiculous exaggeration. Figure you might go through 1-2 heads a week (at $1 a pop if you buy 5 through the above link), plus whatever your juice costs - for me about a $5 Mt. Baker Vapor 15ml bottle a week. That's about two days of my cig budget, so I'd be saving if I hadn't wasted some money buying too-expensive equipment and juice from a local cig shop that didn't understand vaping off the bat, get addicted to toys and buy a bunch of things (including expensive glass Protanks for my citrus, cola, and cinnamon juices), and buy twice as much of all that stuff because my wife gets one of everything I get.
My sig line says I've spent a lot, but here's what I got for that: 6 standard batteries (4 more on the way), 4 top-coil clearomizers (that I realized I didn't like and switched to Evods, 17 Evods (2 that the wife and I broke before learning about "tank cracker" juices," 11 are still in the mail from Fasttech just because they're so cheap), 4 glass Protanks (2 are still in the packaging), 15 spare coils for the Evods and 5 for the Protanks (one package is opened, showing only one missing so far), 4 chargers, a toolbox from Home Depot to hold all my stuff, a pack of pipe cleaners to wipe out my tanks with, and about 15 bottles of juice (plus an "e-ashtray" I made drilling holes in a 2x6 cutoff). That's a virtual arsenal, and I should have enough hardware plus the replacement parts to maintain it for two people to use for 6 months or more, buying nothing else but juice. If you don't go overboard (or waste $100+ like I did buying overpriced/inferior products before learning my lesson), for $100 you should have a setup that will last for months on a few weeks' cig budget.
Anyways, the point I'm tryin to make here is ... I'm probably an estimated 12 smokes a day, but sometimes up to 15. So not quite a pack a day, but Im still pretty hardcore abt my smoking. Its that "love-hate" thing that I know all of u understand. I started rolling my own, and it basically cost me abt $35 every four days. So will I save money? Almost CERTAINLY. Its just like "hmm, I now saved enough money to buy myself a combo meal at a fast food place!" lol jk, u could get something *special* with *that* kind of money~
Speaking of.. I saw that thread one day on the "things u buy with the money you saved from quitting smoking" or something of the like, it was pretty cool!
