Seagate Technology 200 GB USB 2.0 and FireWire External Drive ( ST3200823A-RK )
Works exactly like it's supposed to.
I've been using mine for several weeks now, mostly to store backups of my music collection, and I've been perfectly happy with it.  It works fine, it requires absolutely no setup, and the speed with which I can access it over the USB connection is acceptably fast.  And when mounted vertically on the stand, it takes up very little space on my computer desk.
