I have owned a RS V2, I think it is a great 
mod, one of thew great things about it, is that you can replace the switch yourself when it goes bad.  For the money, its kinda hard to beat, it looks nice, its comfortable to use and it is cheap.  My suggestion would be to 
buy just the 
mod and a charger and pick up some IMR high drain AW 18350s, but thats my opinion and personal preference.  If you have anymore ?? just shoot me a pm.
