Tom at Wild Hare has a nice A123 starter package:
A123 battery starter kit
We now have a nice kit to get you started with the A123 battery technology. The kit includes 1 2500mah battery pack (sufficient to properly power any R/C aircraft, really), a Cellpro 4S charger, charge cord to connect to the battery pack or any charge jack, and one Smart Fly super switch

Be careful they may not be genuine A123s to the best of my knowledge (although I may be wrong), A123s only come in 1100 and 2300mAH capacities. It's either *not* a true A123 or they're overstating the capacity. Either way, this does not appear to be particularly ethical.
