Stay the heck away from the 15 minute chargers....while they do work, they are very hard on the cells. You definitely will not get anywhere near a 1000 cycles out of them using the 'nuclear' chargers.
The Energizer 15 minute charger (CH15MN) is one of the worst in terms of how hard it is on the cells but one of the best in terms of speed....hits them with a BLISTERING 7.5 AMPs.
Heck, even the Energizer 30 minute charger (CH30MN) hits them with 4 Amps!
Well over the maximum rate of 1C that many manufacturers are indicating.
It's a hair more than $30 but I would go with the LaCrosse BC-900 ($39).

If you wanted to go top dollar, I would get a Maha MH-C9000 ($60).

There are many other smart chargers that perform well, but the two above are a couple of the BEST and most popular right now. They not only charge your batteries but can also discharge, condition, analyze, etc. them as well. These features really help out when you start getting into using rechargeables quite a bit and want to sort out the under performing cells.
