Tiger Direct has a sale (until 4/3) on a Seagate ST320005FDA2E1-RK external USB 2.0 2TB for $159.
I couldn't locate it on the Tiger Direct website (searched both by model number as well as using the menus).
But in case it's now gone, or if someone wants to buy one after 4/3, both Buy.com and Newegg have it for their regular price of $169 with free shipping.
