I've decided on a Drobo to hold all of my media files and I'm going with a USB one for the savings and since I only plan to stream 1080p files. I've found one on ebay here: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&Item=160291263486&Category=80217 It's got 2 1TB drives and it would be about $450 shipped, which is about $100 off. The caveat; it's used and according to the description the HD door is broken. In the description and elsewhere on the internet it says functionality is not effected by this. Should I jump on it or get a new one from Amazon? Or are there obvious alternatives I'm missing for easily expandable redundant external HDs?
