I looked at eBay and couldn't find anything comparable to what I have.  I was given a copy of the miracle piano teaching system, complete with the keyboard and the foot pedal.  It's dusty, cand I'm going to take an army of Q-tips to clean it up.  There's no box, but it has everything else except for the Owners Manual and the warranty paperwork.  In fact, it still has the headphones.

My coworker told me to come up with a fair price, so I was wondering if anyone here has ran across the system, and what would be deemed a fair price for it.

Thank you!

If it has the cord to hook it up to the snes then I would say 125-150, but without that cord and box you'd be lucky to get 50. I've seen one sell complete in box with all the cords for 200ish. It's one of those items that takes a special buyer because it's so big. Hope this helps a little.
