That would be right Paragon has been the number 1 machine I have been after for ages and the same day I give up and put a deposit down on a Shadow one shows up....never mind I'm still looking forward to my Shadow...Just a hypothetical in case I do still have a go at the Paragon (and I know it is an impossible question to answer having not checked it out fully) but is any one game on having a ball park guess as to what it might on cost on top of the sale price to have someone shop a machine like this and bring it up to speed and have it playing well?
Completely depends on the standard of "shop out". Just getting it going, replacing rubbers, bulbs, fuses and a general clean could be done for $150-$200. To address the flipper issue, power supply, solenoid driver, MPU connector issues will add time and costs (depends on the condition).
I'd say you should work around the $35 per hour and then set the standard shop out / recondition / restore.
