New playfields are in the pipe from CPR, that'll run you about $800... not sure if they are doing or have done plastics, those will run you another $150ish. The tube on these are often shot you may need to replace that. Cabinet stencils another $150ish. Depending on the shape of the boards you may need to do some work there, you could pretty easily put $1,500 - $2,000 into it to make it look beautiful. As far as early 80's Bally's go it does have some desirability... behind titles like Fathom/Centaur/EBD but ahead of titles like SBM I'd say. $50 is obviously a complete no brainer, get it loaded in your vehicle stat!
