One charger I bought off of Newegg some time ago, which works great, is a POWEREX MH-C9000. It has several integrated options that do more than just charge. This device can also analyze and increase the charge/life in old rechargeable batteries. If you do get this unit, make sure to read the manual.
Newegg appears to be out of stock, but Amazon appears to have them for around $50, I believe I got this on a shell shocker deal for around $40 with batteries and a carrying case.
Sorry to throw an apple into your oranges.
