Trans Intl. offers the ProStor 2TB eSATA / FireWire 800 / USB 2.0 External Hard Drive, model no. 735, for $168 plus $8 for shipping. That's $0.09/GB, $20 under last summer's mention of a similar drive, and $4 under the lowest total price we could find now for such a drive elsewhere. This 2TB 7200 rpm external hard drive features an aluminum casing, 64MB cache, eSATA and USB combo port, two FireWire 800 ports, and FireWire 400 port.
