The Triton charge is a good all around charger. You set it for the type of battery you are charging though, and it's DC only.
You can use a regulated power supply at home. People use old computer power supplies that can be had cheap.
7 or 8 cell KAN 1050's are great nimih batteries. Nimh's don't need to be cycled like nicads do.
