Did your go bad? If so if the magnets are still glued to the case, you can have it rebuilt for a lot less money then buying new. In my particular experience finding a good condition used is rare, I ended up buying new from a online retailer.
That ebay one is pretty expensive for used, I believe for about $60 more I got a brand new one. For the life of me I can not find one for sale on any websites, I imagine they went on back order again : /
