I own Baywatch and LAH, the only thing I liked better about LAH was the shaker motor, so I added one to BW and have an awesome game that I love to play. It doesn't get much attention from guests, as they flock to my STTNG, but BW has the best combination of easy shots for newbs and hard to hit shots for owners. Still haven't gotten to earthquake mode....
Like someone else mentioned you can probably get BW and LAH for the price of Flintstones if you have the room.
