I thoroughly agree with Eslaudio's suggestion of having two on hand, one to function as a backup of the other. The prices for large drives is low enough nowadays to do that.
You can also just get an individual drive (500 GB is probably the best bang for the buck) from, say, Seagate or Western Digital, and then get an external enclosure from Icy Dock or Macally and put it together yourself. The nicer external enclosures are a breeze to install a drive into. Check out newegg.com, which is my favorite place to shop for computer parts.
I'd recommend an external drive with both USB and Firewire interfaces. If your computer supports it, you might also consider one with an eSATA interface, which can be considerably faster.
Good luck,
Michael
