That looks pretty nice. At least what's visible from the two pics.
As with any game, run switch and solenoid tests. A few RS specific thoughts.
Check that both Red and Ted heads work, mouths and eyes. Those are a pain.
Check that the dozer blade works and that the sensors in front and behind it detect the ball. There's also a third eddy sensor right in front of Red.
The area on the playfield just in front of the kickout hole gets a lot of wear. Look for wear near the fish picture.
Not sure what a fair price is these days with pinflation. The posted price looks a little high to me.
