The backglass is 'ok'. You can see from the pictures that there's some flaking in the red and cracking at the bottom. After playing tonight, I'm knocking the price down to $600 as one of the displays is worse than I remember from a month ago (has a digit out and a segment at the top) and of course it needs new rubbers and cleaning. Here's what I know about it:
wasn't working when I got it
replaced 5101 and socket, started working
played 30 or 40 games on it, then I noticed that the high score was a little weird
swapped back in the original 5101, problem went away (replacement 5101 must have been too slow of speed, a known issue on the mpu-200). Evidently it was only the socket that was bad to begin with.
everything else seems to work fine, haven't noticed any other issues.
