I just sold the one I had. It's a neat game but not really much to it. For home use you don't really need the electronic aspect of it as you manually keep score. All the electronics does is count the number of times you slide the puck as after so many tosses the game shuts off. So unlike real shuffleboard, where you play to a certain score, this one plays for a certain amount of "throws" of the puck.
The big thing about this game that is hard to get is the light that goes in the center of the game. Mine didn't have it as most games the vendors removed them. So if you're buying one without the light and want a light .......... good luck!
As for fun factor.....it is neat to play. When you slide the pucks they come back to you so it's not as if you're looking down a long table wonder if your puck stop on a certain number or if it's a "hanger". Plus it takes up a lot less space then a regulation one!
If the one you're looking at has the light you should be able to get it for less than 500 as they just don't go for much!
