Computer Hardware (and software, etc):

resellerratings.com -- Essential when purchasing computer or photo equipment online. Contains a listing of online resellers and consumer ratings of those sites. I had an experience with Dakco PC Products and just barely got my money back in time after discovering their abysmal rating and reading the horror stories from their other customers. I almost ordered a DV camera from the now-defunct Digital Dog, but was saved by a last-minute check at this site.
