A gentleman in Sun City, AZ has been prescribed to play pinball to help with his eye/hand coordination. He wants to purchase a machine in the $500 range. I would think he should have a good working solid state machine of the early variety.
The gentleman suffers from Parkinson's and that is the reason his doctor recommended getting a pinball machine.
Please PM me if you have something that will work this guy, and I will provide his contact information. I am located in Arkansas and can't help with a machine.
Thanks, Barry
