I have a couple of very nice clean early 90s Model Ms (IBM made, not sure the years, both black and blue labels) that I have bolt-modded and adjusted to work quite well.
US Post Office charges $58 for shipping in a flat rate box (Spain is expensive to ship to from the US) so I would have to charge you $100
I understand that might make the purchase prohibitive. Look on ebay and you might find a better deal if you want to do the cleaning and restoration work yourself.
