Did you just go out and buy the first thing recommended to you?
I use the Thunder AC6 AC/DC 50watt charger. Goes up to 5amps and includes all sorts of connectors. Even has monitoring USB software and a thermal probe. It charges everything including lead acid, and it has lipo-charge/balance, lipo-charge, lipo-fast-charge, and lipo-storage modes. Sells for $55 on Hobbypartz.com:
I never had a bit of trouble with mine. I even covered mine with carbon fiber stickers to look cool.
