$350.00 for a puck bowler with multiple games including Flash is a steal. As long as it's complete (no missing, wires cut to remove major mechs) is a steal.
That said, this is a Solid-State machine; So, no assemblies to cut out. But you need all circuit boards and displays. The only contacts to adjust are the ones associated with the pins. Also a couple to select the game etc. Be sure this is not a con job. Best you or someone you know checks it out that it boots up and plays for the most part. It has a similar diagnostic routine to early Bally & Stern pins. Do the lamp, display, solenoid and switch tests.
If it boots and plays partially, grab it before someone else does.
PS, it is Solid-State, so you don't get the wonderful EM sounds when calculating scores and advancing frames etc. Only sound is the pin motor, pin solenoid buzz and the clang of a chime.
