FRYS.com has the Maxtor MXT C01W010 1TB TURBO external drive for $419.99 with free shipping. This has raid options, so there is a pair of 500 GB drives inside to reach 1 TB.

This is less than an internal 750 GB drive at Newegg! Maxtor never made a 750 GB drive, so it’s most likely a Seagate 72100.10 inside, although it could be either IDE or SATA. Price is $319.99 with free shipping. Limit 1 per customer.
