I've also heard good things about the Gens Ace lipos, plus they're pretty inexpensive. I'll probably end up geting a few different brands of lipos in the coming month and decide which ones I like. I'm sure I'll end up deciding that they all perform basically the same in comparison and I'll like them all far more than my nimh packs, therefore there is know reason to spend the big bucks on a lipo when I can basically get the same thing for alot less. The most expensive one I plan to get is a Venom, I looked at a few different ones I liked at my LHS for $50-$75. I've also heard Turnigy is pretty good for the price. I think their nano-tech lipos are in the same price range. Paycheck in two weeks, then I'm off to Hub Hobby!
