FWIW, I'm looking at the Fantom GreenDrive 1TB External eSATA/USB 2.0 Hard Drive, for $119.99 at MacMall ($79.99 after two rebates are applied). If you need Firewire, MacMall also offers a triple-interface Fantom GreenDrive (1TB) for $154.99 (or $114.99 after rebates). I've been doing a fair amount of research on reliability of drives, speed, temps, things like that, and this is the drive I think I'm going for. I think its innards are by Western Digital, which gets rave reviews by some and rants by others. Fantom itself gets pretty high ratings.
