Supposedly Astroflight is working on a chip that will allow for the charging of A123 packs.
Otherwise, the CV phase shouldn't be long with these batteries, considering that when the voltage reaches about 3.65v the cell is almost completely charged (indicated by how the cell will cause the voltage to skyrocket when a CC charge is going on).

I agree that $80 for a 3S charger is over priced. The FMA Direct CellPro 4S charger can now Charge & Balance A123 packs at 3Amp for $60. However, The Astroflight 109 for $90 will charge Lipo's and A123's but it will not balance them. Are you planning on configuring you packs with balancing wires? I find the whole balacing connector differences quite a PITA. It seems everyone has their own connector and I'll have to get an adapter if I want to use someone else's charger/packs.
