I will definitely not buy the 900 mAh. I don't mind keeping a 6-pack of batteries in rotation to get the best performance. I don't want to sacrifice that for a little better battery life. Has anybody found these RCR123a's locally? I screwed up and forgot to order in time and my revo is sched for delivery tmrw. Vapeworld if they have them in stock(not on website anywhere), may be able to get them here by Sat. BUT, if anyone knows any local/speciality type shops(i.e; photgraphy store or such), please holler. **Anybody in Tampa Bay area looking to get rid of RCR123A's?
