If your friend got this at a "decent price" and doesn't mind putting a bit of money into it, go with a Hardtop for the playfield. Its basically a plastic overlay with new art that covers the old playfield. You would need to remove all the topside pieces (not as hard as you think) and sand the inserts. Looks AMAZING when finished!!
Just search Outside Edge Hardtop

Plus it gives you a chance to thoroughly clean everything.
