You can get this straight up at Circuit City for $99.99 (throw in coupons to bring it down if you have them, or buy 2 and use the $40 off $199 in-store coupon floating around) and use either FW CashBack or Live CashBack to bring a it down a few bucks, or buy it at Bestbuy and then PM to CC to get the 110% PM to bring it down to $92 (remember, you need to make the purchase at BB and THEN PM it, or else it's just a 100% PM).

Specs:

Warranty - 5 years
Drive Capacity - 500GB
Drive Connectivity - USB 2.0 and FireWire 400
Rotation Speed - 7200 rpm

CC Link

BB Link

I know it's not the best of deals, but this is at least warm with the firewire (even if it's 400).

Hmmm...
Office Depot currently has this for $99. If BB will price match, there is a 10-12% BB coupon right now (good for external drives), which makes this $80ish. (If you can get 110% PM + coupon).

Might give this a shot after dinner, not hot but definitely warm IMO.
