I hear ya. Even though I do have one 900mAh eGo type battery setup now, I do like the smaller, more cigarette size style batteries very much.
I have several KR808D-1 batteries. That's what I started out with and I am comfortable with. It's especially nice now that I've found out I can get adapters so everything will work with everything else.
Check out the 808s here...http://www.myvaporstore.com/KR808D1_E_Cigarette_s/44.htm I have not ordered from them yet, but I will real soon, I've been told by several people they're a good place to order from.
