$300.00 is a good price, but if you can only find room for one shuffle alley, I would recommend a 1960's machine. That machine appears to be from the fifties. The 1960's machines are better because they have a larger variety of games to play on the same machine, and in the sixties Formica was used for a surface. It holds wax better. I have restored five or six shuffles and a ball bowler. In my opinion, I would say that United shuffles are superior to C.C.'s. Personally the 1960 - 1962 United shuffles are the best.

These games are prone to having gummed up parts. You should really take apart all the parts and clean them if it doesn"t work properly. But anyway, back to the original question....$300.00 is a good price.
By the way, shuffles are 9' and ball bowlers are generally 11'.
