Spending spree tonight! For equipment, from litecigusa I bought a Joye EGO-C Twist 650mah, a Smoktech Mini 450mah EGO, 5 x 2.3ml cartos, and 5 x 6ml cartos. The little 450mah unit looks to be about the size I'm after and about double the battery of my V2; but I'm intrigued by the idea of the variable voltage on the 650mah. Figure I can start with the pre-built cartomizers and move up to the RBAs next time I need equipment. As far as juice, I found many people on this site praising Mom and Pop's Vapor Shop -- from them I picked up 30ml of 48mg nicotine PG, an additional 30ml each of PG and VG, the RYO and American Blend flavor concentrates, as well as some caramel and fruity concentrates for my wife. The tobacco flavors both had reviews/descriptions with elements of what I (as a recent analog smoker) think I'm looking for, and I'm interested in trying to find my sweet spot for nicotine concentration, so this should be fun.
OCD kicked in, and did some rough calculations -- given the varying estimates of how much e juice is equal to a pack of smokes, I'm figuring, given what I've just spent, I'll be coming in somewhere between $.50 and $1.50 per pack of factory-rolled cigarettes, or between $1.50 and $4.50 per pack of RYO tobacco. Considering I used to spend about $10/pack of RYO tobacco, I figure I'm getting ahead.
Once again, thanks to all who helped me figure out what I needed! Lucky I found this site.
