Since I am working in my 4X, I will be selling my 3X (76) in May. If anyone is interested, please pm me and I can tell you the details:

Gigged extensively
Joy stick a little quirky, but in tact
One button, 1st pad, is a bit loose, but works
Some scratches on the board from where I put the mixer (until I got a mount)
Not too much else
Screen works well and bright
Key bed is in perfect shape, I don't play banging style
