Without having seen, heard or tested the synth in question it is hard to tell the price. It could be just the keyboard that needs some serious cleaning, or it could be that the electronics needs major repair.
The best advice would be to have a professional service shop have a look at it and determine approx. what needs to be done.
If it is in really bad shape, I wouldn´t give more than 100 USD for it.

i have a chance to pick up a used mono/poly but it is pretty fucked up.
only some of the keys work, and when they do there is no way they make proper tones or anything much different from one another in pitch. some of the parameter knobs such as the scale do not seem to have any effect. the arpeggiator still works and so does the ADSR and a bunch of other things. but basically at this point is is a noisemaker only. cosmetically it's ok although the right wooden side has broken off and is hanging.
i've seen these things going for anywhere from $500-$850 or more in excellent working condition. what kind of price do you think this one is worth?
