Pick up a new PowerSonic PSC-61000A for around $35. It's the charger that EcoCharge puts their sticker on and calls an SC-61 (if I'm thinking of the right part). Otherwise, check out the other PowerSonic chargers and find one that suits your needs. Oade was selling a smaller one that worked well with 6v 7mAh batteries, but maybe less ideal for large batteries like 12mAh.
