I have had excellent results with the Maha C777 plus
MAHA MH-C777PLUS-II Universal LCD Battery Charger Analyzer Conditioner for NiMH & Li-ion Digital Camera & Camcorder Batteries
Its a little slow at 880mA, but does an excellent job. Also has a temp sensor, burn testing function, and switches from NiMH to Li-ion. And the price is nice too.
