I was getting ready to ask the same question. I am quite happy with my original Tornado 650mah bats, however...I would now like to move up to 900mah bats. I don't really want to worry with regular battery types...happy with what I'm doing now. Who has the best price on eGo-type 900mah bats, or starter kits??
PS: I'm not ready for a "Twist" variable, and the 1000mah are just too long...Thanks!
