After the CSR offered me a free HR20, I decided to go the route of attaching a 2TB (or less desirably a 1.5TB) eSata drive. I figured Fry's would stock this but they don't. So, where is the best place on-line to get it and what would you recommend to get? We've had good experience with our 750GB Free Agent Pro we got about 2 years ago. Thanks!
