Dang HauntedMyst, that's one
MEGA cheap VV battery. Wish I'd known about it earlier haha, got good reviews too! I might just pick one up anyway
OP: You can get oodles of Kanger booty from Sun-Vapers
here. Decent prices too.
As a small tip, and nothing against kits, they're great for some people... but they're typically overpriced and usually involve not the best gear (or just overpriced). I'd recommend saving and getting a small budget to use and getting something like that X6 and a decent BCC and/or some cartos or i30s, etc (Good to have options, especially if you have multiple flavors). Even if you don't wanna get into rebuilding, the heads are dang cheap and well maintained should last a few weeks up to a month+.
Even the
eGO Twists are hella cheaper purchased separately. And if you don't wanna use fasttech (I can't speak for the site, I've never used it) I know you can get the same battery for around $20 at plenty of vendors.
Just speaking out of experience here. I bought a kit once and was way disappointed and later realized I could've gotten a setup twice as good for the same price. Kits always get a big

from me, unless you are looking for something specific like
The Vapor Zeus and similarly (slightly) unique kits.
More bang for your buck, IMO.
