BLANKETY-blank DURN! I just bought $150 of stuff from them last week! (Graduation present for one person, bribe for my sister)
I'm probably about 2 months "ahead of" the O.P., and still smoking but trending away from real cigs fast.
I know everybody likes the 510's but I prefer SmokelessImage and Bloog with Bloog cartomizers. I suggest ordering 2 batteries, 1 usb charger, and 1 of the heavy-duty wall adapters (the 1.5 amp, not the .5 amp!) and a flavor variety-pack from Smokeless image, and 1-2 flavor variety packs from Bloog. Once you know which of those flavors you like, you can ask for more juice advice here. You will quickly realize you will want to refill cartomizers a few times each.
In a couple of months at the most, you'll want to go to a bigger battery. I also hear tell you'll want to try cleaner delivery systems like clearomizers or tanks, but IMO that can wait until you've found your flavor. Smokeless Image also has a bigger battery that is compatible with their small ones.
Their 78MM (and 68mm) cigarette-sized batteries are voltage-regulated so once you find your flavor and carto resistance, you get steady results, from straight-off-the-charger to nearly-discharged. Same goes for their bigger (X2) long-life batteries.
I get my best vape (lots of flavor and vapor) from Volt or X2 batteries with Bloog cartomizers.
If you read here long, you will see that there are two main surviving "thread types" for e-cigs, and another 3-4 almost-popular ones. 510's and 808 (kr808d-1) are the main ones, with 510 the most-popular by far and therefore the easiest to get a variety of things for.
But I like the Volts which are "808"s.
1. The "channel" at the bottom is easier to get extra juice out of than on a 510.
2. The cartos can stand on end without tipping over.
3. There are also voltage-regulated and controllable-voltage 510's, but 808 Volts
and X2's from Smokeless Image have been robust and voltage-regulated for awhile,
and their customer service is great. Bloog 808 batteries appear to have similar
specs but I haven't used one for very long.
High-voltage vs low-voltage does not matter BY ITSELF, it is watts that matter, and that is (volts X volts)/resistance. Voltage and the resistance MUST be compatible for battery safety (you can actually get hurt from abusing a battery too-severely.) You can find charts and articles on this. I like the Bloog cartos because they are a teensy teensy bit lower-resistance and give me great vapor on the 3.6-volt batteries.
