Thanks to you both. I have to say, Goodwill of Tucson was really, really good after this incident. I heard right back from them, sent pics of the broken machine, and got a refund all within hours. I'm sad it didn't work out for both of us, but at least they were very responsive and fair.
Leonf, that is really, REALLY kind of you. I'm actually in Tulsa but troll the Wichita CL every once in a while. Have yet to buy a machine there, but they seem to have a lot of good deals.
