Buy.com now has the 250gb Western Digital External Hard Drive for $99.95 but it is $89.95 if you pay via Google Checkout. Under $0.40 per gigabyte is very good for brand-name external storage. The drive is dual option (so you can use either firewire or USB 2.0) and has a built-in USB 2.0 hub. Shipping is free. Sales tax is not charged (except CA, MA, MD, TN).
