I've playtested it and love it. On my 2nd game I hit the elusive 2,000 point divot on the 3rd ball, and didn't knock it loose. This is a wonderful coin-op, and loads of fun.
And Bob, you mentioned the #1 problem with making these old games, learning the rules. Unless you find an owner of a particular coin-op table, it's nearly impossible to find out what the rules are. The nice thing about doing bagatelle and plastic toy pins is that the rules are much simpler in most cases.
