newegg offers the refurbished Western Digital My Book Essential 1.5TB USB 3.0 External Hard Drive, model no. WDBACW0015HBK-NESN, for $64.99 with free shipping ($0.04/GB). That's $10 under our April mention of a new unit (which required a rebate) and the lowest total price we could find for a new unit by $57. This drive is purported to run 3x faster than a similar USB 2.0 device when connected to a USB 3.0 port. It also features password protection with hardware encryption. Offer ends June 17.

A 60-day warranty applies, although it's unclear who backs it.
