Futaba cdr5000. Lots of money, lots of charger.. tells you everything you need to know about all cells. Discharges at silly high amps (if you want) and is a very user friendly charger.
I used to have a ce turbo 35 gfx. This is a bomb proof charger. Works extremley well, but the futaba can tell you information about individual cells as you charge/discharge them, i found this to be the only advantege over the gfx. The ctx is used an awful lot around here (north wales) and i dont reallly know of anyone having any problems with them. I would save my money for a little bit longer and go for something you wont ever have to replace again.... the gfx or the cdr. Hope this helps a little.
