Take a look at this one from Hobbycity. http://www.hobbycity.com/hobbycity/s...lancer/Charger

They have been dropping the price on this one for a while. I think my wife paid about $38 plus shipping last Xmas. It has proven to be an exceptional value, and many people on this forum will vouch for it's quality. It runs off 12V and will balance charge Lipo/Lion/Life as well as standard charge Nicd, Nimh, and Pb batteries. I love mine and wouldn't recommend it if I wasn't 100% satisfied with it.
