MacMall offers the factory-refurbished LaCie Porsche Design P'9221 500GB Portable USB 2.0 External Hard Drive, model no. 9000126, for $49.99 with free shipping ($0.10/GB). That's the lowest total price we could find by a buck, although it was $5 less back in May. (It's also $37 under the lowest total price we could find for a new model.) It features an aluminum housing designed by F.A. Porsche. A 90-day LaCie warranty applies.
