I've got a Yamaha PSR-185 keyboard in very good condition that is going unsued now. It can come with a metal height adjustable stand and has the music book holder which can be removed if required.
There is only one mark on it - a tiny bit of warping on the left speaker. It sounds serious but honestly its just a small cosmetic mark.
Any questions just ask, there's some photos in the post below. Unfortunately it doesn't come with the original box and any required postage would have to be discussed (would prefer to keep it collection only at the moment from Bishop's Stortford in Hertfordshire).
