ABSOLUTELY! The price is reasonable for a great game in good shape
As mentioned, check the backglass, front and back. Check the boards in the backbox for bunt connectors, and shody repair work. Take a look at the base of the ramps, likely to be cracked, which is 'ok' but if it looks too bad, talk down the price, ramps aren't cheap. Many Earthshakers any more have significant playfield wear despite the mylar, so take a close look at the un mylared areas that will not likely be clearly seen in full playfield photo shots.
I own an Earthshaker and have no regrets and no plans to sell it anytime soon.
