20K eh,phew    I take it that your search for a MM continues,
Most that I saw one go for was in the States and that went for U.S.$12.500.00 I thought that was a little much but having said that MM is a machine that is only going to get more expensive with most that are out there in collectors hands and those collectors not wanting to part with them its only going to push the price up.I myself cannot remember the last on that sold in England, Its been that long since I have seen one for sale here.
MM is one sought after machine.
