I have tried to keep rough records of machines I have in a spreadheet, paid, where from, colour model etc......stupidly I have actually numbered them on the machines, so forget which one is which. Anyway having sold a few Hi Tops over the last year I did an audit and found two machines I never knew I had, well I knew they were there, just not the numbers and descriptions. So thinking I had 32 left documented, now I have 34
Maybe I am selling them too cheap as well, I am sure you saw the one below on eBay last week sold for 700, missing a large chunk of the base and the coin tray bumper
Might get around to auditing rest at some point..
