I'll be one of the few on these forums, and recommend the ego-T attys. I've been using the 1000mah batteries for the past 4 months, and I'll suggest you order the attys from thevaporpro I don't have the usual problem I've seen from other posters about leaking and such--if anything, I make sure to order all of my hardware from them. They carry some decent eliquids, as well.
