Reply to FS or Trade: Akai MPK Mini

Hello all.
I have an Akai MPK Mini is pretty good condition. At one point I did the mod for the pads where you put a piece of electrical tape under them for increased sensativety. It's subtle but they feel pretty responsive.
All keys pads and knobs work fine.
The bottom of the unit has some scratches. I tried to show it in the pics. They're not deep and of course do not affect anything.
Asking $50 plus shipping.
