Exact same HD at BestBuy almost 2 months, but the rebate was greater during a special week. Ultimate cost to me was $27.
NOTE: This is an IDE ATA drive. I ended up having to buy an interface card in order to install it on my new Dell Dimension with SATA (Serial ATA) connections. The interface thing was like $17 delivered. If you need one, here's a link I used:
Check out the top couple of products in the list (with or without additional cabling).
Another item worth considering (I bought one of these, too, last month), is a USB 2.0 external Hard Disk enclosure, by Adaptec. $50 at BestBuy or CompUSA (other brands are cheaper). This thing is really smart! You can stick any IDE drive into it, set the HD jumper to MASTER, plug in a couple of cables to the HD inside the contraption, and then hot swap your HD into any USB 2.0. Really, really fast and convenient. There's a driver CD if you must use this on a Windows 98 machine, but otherwise XP OS natively sees it. Totally cool. Totally.
