i just got back from best buy. i bought a 320 GB external western digital hard drive there for only $180. it looks a little funky, but has these awesome lights on it. here is the link:
Glad you're happy, but you might have done quite a bit better with a bit of shopping. I've never found "the best deal ever" in a best buy on anything.
For comparison, I just purchased a 300GB HD for $80 (no rebate hassles, free shipping). Enclosure should run $35-65 depending which one I choose. Or if you really want cheap, just grab an IDE to USB cord for a few bucks.
