The cheapest site I know of is newegg.com. You want to review the following:
1. Price (is it in your range?)
2. Size. If the hard drive has "GB" at the end, that means it is rated in Gigabytes. 1,000 "GB" = 1 TB. A "TB" = terabyte. So a terabyte is larger than a gigabyte. If you just web surf and do email, microsoft office, etc, then you do not need a hard drive the size of 1 TB or more. If you do video authoring or store lots of pictures (many hundreds, etc), then you should consider the high GB drives or even a TB drive.
3. RPM - this is the speed that it works at. Higher = faster = better.
