My experience has been that how I charge isn't so important as that I charge. I've got the usual collection of wall warts, and when I know my schedule I'll use them when I can. When that's inconvenient for whatever reason, I use an MRC SB969 to charge my NiCads and NiMHs. My LiPos only get used with an FMA Cell Pro.

More important than the charging, I think, is the checking. Get a loaded voltmeter. I've gotten into the habit of checking my batteries before each flight. It hasn't saved me any trouble yet, but I have no doubt that it will at some point. With a good charge-switch, it's very easy to do. I got tired of the cheap little switch harnesses, so I bought a bunch of decent ones for about $12 each.
