Unsure of the going rate, I think I have seen a few around the $3000 mark, but I'm sure someone else can help you with a price.
Look out for wear, nearly every one I have seen has had extremely bad insert wear and no decal left on the spinning wheel.
Haven't played one for a few years but I do remember it being a good game, not deep but satisfying to hit those gofers, the drop ramp to hit the hole in one is a fun feature.
