I just got this not long ago and it's cleaned up superbly. I've read a lot of nightmare stories about the MR80, but I've gotten very lucky with this one. All the functions appear to work. The preset buttons respond immediately, the up and down auto scan works as intended. I can manually tune stations with no problem at all and the headphone amp sounds very good. It also seems to pull stations in very well. It was pretty grimy when I got it, so I'm very happy with the end results.
