Buy.com has the 200gb Fantom Titanium External Hard Drive for $59.95 after a $20 mail-in rebate valid through 3/31. Shipping is free and there is no sales tax (except CA, MA, MD, TN). These work with both PCs and Macs and connect via USB 2.0. Also of note: Buy.com has a new and very-rare $5 off $50 coupon valid in all stores for new customers through 3/31 and new Google Checkout users can get a $10 off discount for signing up (but you can't get both).
