How many cells are you looking for it to charge? Your best bet may be a Super Brain 959, those can charge up to 8 cells at up to 4 or 4.5amps (one or the other). They do have a tendency to false peak sometimes, but there are modifications that can be done to help prevent them.

My vote is for the Superbrain 959. As stated, it charges up to 8 cells, and does go up to 4.5A: charge current range: 0.5A to 4.5A in 0.5A increments. I've made several adaptors so it charges pretty much all batteries in my house now - very useful!
