I'd like to learn sometime, but I'd rather to with something prebuilt for now. And I'm not sure where I'll order from yet. I've heard there's a lot of knock off sites.
That's a good decision IMO, the thing about rebuilding is that it's fun and you can get great results, but it can also be immensely frustrating at first -- better to get something that gives you a high-quality and reliable vape to fall back on first.
As I said before the Kanger Aerotank is a good bet. Aspire also makes some good tanks ( such as the Nautilus ) but these are going to cost more. Kanger includes a nice illustrated instruction manual with their tanks, so you shouldn't have any problems figuring out how to use it.
As UncleRJ posted above, Fasttech has great prices on many of these items and a 45 day return, 6 month replacement policy. I have not used that particular vendor yet, but they do have pretty much the best prices and a very good return/replace policy, so I probably will in the future. They are a Chinese vendor, I believe, but I'm not sure how that will factor into shipping times. UncleRJ, could you weigh in on this?
I have used vividsmoke before and was very happy with their ship times ( they are based in Irvine, CA ) and they are a reputable vendor. Their prices are not as good as fasttech's are, however.
Since you're using a digital mod with short circuit protection and other safety features, you don't have to worry too much about what battery to use. Just be aware that a battery's mah rating is roughly equivalent to capacity, so more = better, and that for a VAMO it should be either 18650 size or 18350 size ( VAMOs have a threaded extension section that can be taken off to shorten the chamber, that is when you would use a 18350 ) Fasttech has some 18650
Panasonics,
Samsungs and
LGs that are sold in 2-packs at very good prices, any of these should be good for you.
