Since the Sorcerer fell through I have the itch to pick up another table, and I came across this Nitro Ground Shaker this morning. Here's what the ad says:
1978 Nitro Ground Shaker. Good condition, everything works. Minor playfield wear, and some of the backglass paint is chipping from the bottom. Otherwise in good shape. All lights, coils, switches working. $550 Price is firm, no lowballers please.
Unfortunate about the backglass condition, but it is what it is. Does this table look worth the $$?
