Well I will be honest I really don't know. I would guess that it will be worth less than a vendo 110 since its not mechanical and most collectors prefer mechanical crank handle machines. Also the not cooling thing is a problem that can kill the price. That basically weeds out the casual collector or first time buyer as they don't know much about these machines and have no idea how to fix it. Personally I would never sell a machine in good condition that is not working. By doing that you cut your customer base by more than half. Have you checked the easy fixes? Wiring, fans, thermostat??? If its an easy fix it will be well worth doing. If it was working and in good clean condition I would say maybe $500? Thats totally a guess. Due to it being a scarce machine you may find a collector that wants it or even better if it on ebay two collectors that want it
