2 things to mention from my own investigations into NiMH chargers for my Visor Deluxe NiHM batteries last year
1) Regarding "fast" chargers, there were postings in a number of the photography newsgroups that "fast" chargers generate more heat in the NiMH batteries; and that said heat reduces the lifetime of the batteries.
I do know that the latter claim is true, but I don't know how significant this is (i.e., do your batteries lose 1 month of life in a lifespan of 2 years, or what?) It's a big issue with photographers, who go through rechargable batteries like peanuts.
2) I bought a Maha fast/smart charger (similar to the MH-C204F) when I first got my Visor, but gave it away after a few weeks. The contacts for the batteries were cheap metal clips, and bent when the batteries were inserted, forcing me to frequently have to bend them back to make contact. Also, the plastic cover broke off after a couple of weeks.
I replaced it with a cheap Radio Shack wall unit (catalog #23-335). It's slow (which appears to be a good thing -- see above) and it's not smart, but it does have settings for NiMH high-capacity batteries. And it's quite rugged. And it's cheap ($13)! I've used it for almost a year with no problems at all.
