I honesty can't say I've played a shuffleboard table besides in the bars. But, I do find them very fun and easy to play. If I had the chance, I'd trade out my billiards table for a nice one. Everyone knows how to play shuffleboard, but pool tables do scare some away.
As for most expensive to buy, will not by a long shot. Bang for the buck and easy to keep going is a big plus. While they are long, they are thin and don't need all the play area as a pool table for cues.
Even my wife likes shuffleboard tables.
Get one if you have the chance. I've thougt about selling my pool table for one, but there are no shuffleboard tables around here and I can't build one.
