Cool. I just sold my 20GB backup to someone, I could've gotten more (I'm sure yours will go for well over $700) and I would have really hated to see that person just turn around and sell it (the main reason I was willing to sell for what I did was because he's going to keep it). Good luck in your sale. I strongly suggest you keep at least one spare though. My 30GB backup has been my main unit for 3 months now.
