I've been using this Vapor Shark DNA20 for about a week now its a tiny little beast and they only go for $170. Which put them in the same range of a ProVari. I'll take the DNA20 over ProVari any day not that the ProVari isn't good or anything I just like variable wattage over variable voltage.Hunting for DNA20 mod
Edit:Also the innokin Cool Fire 2 is a pretty desent Wattage device. I suspect the price should drop any day now like most Innokin products. I mean you can get a VTR for $60 now.
