I just jumped on a good deal on a 160GB Western Digital Caviar SE with 3yr warranty (details). A $70 rebate and $30 rebate (linked on the product page above) bring the price (before tax) down to $99, which yields a nice comfy $0.62/GB cost. Bought it at my local Best Buy to avoid shipping charges. Comes with a controller card as well. Not quite the 250 GB behemoth above, but enough storage for me, from a more reputable (IMHO) manufacturer, better warranty, and a lot cheaper per gig.

The rumor on the deals forums is people are finding 200GB models in 160GB boxes, which makes it an even better deal. I wasn't quite so lucky, but still find the 160GB to be a great deal.
