Thanks for all of the replies. I had checked Ebay completed sales, but there were so few that it was difficult to get a feel for what was the going rate.shipping is complicated too though - obviously the packing is long gone and because I've never moved it I've never needed a flight case. Hopefully there are a few aspiring CZ1 owners in central Scotland.
Will be sad to see it go, but sometimes it goes more than a year without getting switched on, so it would be better in the hands of someone who really wanted it (and my fingers are too big for a CZ 101!)
