I recently bought one, in immaculate condition, for about 25% of its retail price in 1979. Be interesting to hear from if anyone has actually resold, say a middle of the road PP, one year after purchase and made money. Personally I didn't even think about making money. I own now own another lovely, obsolete piece of machinery, Just like my 18th century clocks. Each represents a deliberate choice and will never be sold Regards Keith
