Hi folks. I have a chance to buy an old cabinet incubator cheaply. (under 100) It 'works' according to the owner. Can components be purchased to upgrade this? Like the turners and and electric thermostat, etc, if it needs it? Should I take the drive and get it and try to fiddle with it? Or should I hold out for a used dickey or sportsman? Part of me wants to just plunge and order a new one. I know if I don't jump on this one, it will be gone..... advice, thoughts please?
