Answer 1

I'd try Amazon.com. That's where I got my Seagate. Or, if you know what brand and model you want, go to one of the shopping robots (Shopzilla, BizRate, Buy.com, Froogle, etc.) to get the lowest price. Check Consumer Reports; they had a report on hard drives just about 2 months ago; you can find them at your local library.
