Don't have one in my gameroom, but I bought one for my mom because she loved it when she was a teenager. I'm not a fan of too many games from that era, but I enjoy JP quite a bit when I'm at my folks' place.
As a fan of 90's and newer games I still have a lot of fun playing JP, and I think that says something. It's simple, but addictive IMO. I also enjoy playing pinball by myself primarily, and as fun as it is solo, I find that multi-player games make Joker Poker even better. For a game with only targets it is a surprisingly fun pin. Fast forward to a game like WH2O that is almost all ramps and I don't have near as much fun, just a matter of personal taste. Long story short, I say give it a try if you have the opportunity.
