I can vouch that the vamo v5 is affordable, and perfect if your only going to use it 1/3rd of the time, that's exactly why I bought it (I'm mainly a mech user), the one and only con is that it's press fitted in 2 parts (you can't tell unless you bend it REALLY hard), if you sit on it really hard, or maybe whack it on the corner of something (I mean a really hard hit), it will split in two because it's two pieces of stainless steel smushed together very tightly. It' an excellent vv/vw though, and has more capabilities than most vv/vw's out there. The press fitting sounds cheap, but it's really solid, looks good, got a bright led screen with ohms, watts, volts, battery life, battery & short protection, average/rms setting, and can even turn the screen off if you want. For 29 bucks you can't beat that, that's my personal pick.
~However if your looking for something nice looking, or that has a better shell then I'd suggest provari, evic, smoktech vmax is really good, I'm also a huge fan of innokin because they've never let me down, they have sort of a small lot to choose from however.
*They have a 26650 vv/v3 called the E-Huge

, it's ridiculously huge, almost stupid cool, I think it looks pretty rugged (in a good way) and you can STACK 2 26650's, just a thought if your open to it. It'd look like carrying around an olympic baton though, not sure if you want that

.
This is a "clone" website that has some lower priced ones, they look identical to the "authentic" ones because most use the same chip anyway, there's really no point in spending alot on a VV/VW mod unless you know you want it for the rest of your life. And if that's so, i'd seriously look into getting a DNA20 or 30 mod

I've got a futura coming at the end of this month.
