Good place to start. MAHA are on of the best, Lacross is another. I've purchased from http://www.thomasdistributing.com/Maha-Chargers_c_1022.html before
I have a c401FS and a c9000 and a bunch of Sanyo Eneloop and Maha Imedion.
Most of them use an external power supply and either come (c401) with or you can buy separate (c9000) a 12v adapter to charge from your car or from a 12v battery charged by your solar or wind system.
When I buy batteries I number them with a sharpie and make a spreadsheet then run them through a refresh/analyze cycle on the 9000 and note the tested mAh. Then once a year or two I'll do it again so I can see if any have degraded. I have some old Sanyo 1650mAh cells from 1999 that still had 80% of their capacity in 2009 when I last tested them.
I usually make a habit to pull the batteries out of gear in the spring and fall and test the gear then top off the charge.

The next step then in preparing for a small scale solar system is realizing those old automotive cig lights plugs are junk. I started looking for something better and found that a lot of ham radio operators use anderson power poles and they are somewhat of a standard for ecomm. They are not perfect but better than the old round cig plugs. I bought a couple packs of those and a roll of wire then a couple male and female cig plugs and made a few short adapters to go between the two.
Then if you do that you can put just a couple of the old round plugs on your solar system and a few of the power poles. Then make up some replacement power cords using power poles for some of your gear. have extra flexibility that way and you can just buy something like http://www.westmountainradio.com/content.php?page=RIGrunner to eliminate some wiring.
