Be Aware!
Good point, Suregrip. He knew the thing was a POS, so why didn't he save himself the the frustration/time and just unload it on one of those other interested buyers instead of collecting a deposit up front? Maybe to try and guarantee getting what he wanted for it? What he knew nobody would really be willing to pay?
I'd say it boils down to a shady deal caught a sucker. And they both lost out - go figure.
