Just got a 250gb external Iogear hard drive with USB2.0 and firewire for $189.00 with free Fedex from Newegg.com
That should handle my backups for a while. Only problem was it came with FAT32 and 8 partitions, but a quick look inside showed a WD Cavier hard drive. Quick download and I had it formatted with 1 250gb partition.
