icy, I have a used 55g I was planning on cleaning up and selling. I was hoping to sell it with the stand though and wanted to get a little more then $50. I don't think the glass has any dents or scratches in it, it just stinks right now because I haven't had the muscle to carry it outside and clean it up. Probably not what your looking for in terms of a fuge, but I didn't want you to see it in a couple of days and wonder why I didn't mention it here.
Not exactly in the Dover area, but in the PARC forum take a look through the recent threads. There are a ton of tanks for sale right now. Might be worth the gas money to take a little drive. Good luck.
