One for the Mac crowd: A good price on a 1TB external drive with quad interface - Firewire 800/400, USB, eSata.
It's 2x500 GB drives as RAID 0/1 - but these can be replaced and/or upgraded with higher capacity WD Green drives later, if desired. In general, external drives with a firewire interface run above $200, and that's for a single drive. The Studio Edition range seems to get good reviews as well.
This is from the HT January 2010 catalogue.
wow that's cheap
apparently lots in stock as well around 40-50 at each store
