I love those useless little "gift" GC's WorstBuy gives you when you buy certain products.
I'd go with the Maxtor D740X series. FWIW, my last 6 hard drives have been Maxtors, and each have performed beautifully through ALL I've put them through (high PCI clock, excess shock, direct exposure to heat), not to mention the countless formats, installs, defrags, and power on/off sequences I've run on my test benches. No issues with bad sectors, data loss, data corruption, or drive performance.
Newegg has the 80GB Maxtor D740X HD for $173, and that would be my choice if I were in your shoes. But to each his own.
