I'd get the DuraTrax IntelliPeak AC/DC Pulse Charger.
1) It's 52.99 (on towerhobbies.com)
2) discharges and charges NiCd & NiMH (only Sub-C Cells)
3) Know a friend who has it and hasn't had trouble with it (says charger gets a little warm to hot sometimes [keep a fan near vents to cool off])
4) Can change amount of amps on type of battery:
(NiMH = 0.5A - 3.0A)
(NiCd = 3.1A - 6.5A)
5) Choice of Slow Charge, Peak Charge, & Discharge
6) Can charge 4 - 8 Cell NiMH/NiCd batteries
Sounds good, but just my opinion, go with whatever you want, just felt like putting my 2 cents in 
.
I wouldnt get one of those I had one that I used to charge batts a few years ago when I was just getting into rc and later used to charge rx batts, but somthing went wrong with the AC part of the thing, and now it blows the fuse no matter what the second I plug it in. It still works if I hook it up to my starter box battery though. It also only charges up to 3 amps without a power supply.
