Just seen this for sale again on Ebay at around £350, I bought in 1992 and sold for £25 to a student in 2009. It came out in 1987 and while it was a lovely machine to work with, once the circuit board has gone you are stuffed. My bobbin winder went first, not a problem but maybe a sign of things to come.
I do hope people do their homework before they attempt to buy.
