Aside from jumping up two skill levels (APA) in one year, the best thing I can attest to with having my own table at home is that I rarely ever watch television anymore. To me, that is a good thing.
Also, the comments about "it makes doing the laundry easier" hits close to home as I am always shooting while in between washer/dryer cycles. And, like another poster stated, I can't help but shoot a few balls whenever I walk by the table. Me being retired, I find myself shooting for an hour here, a few minutes there, another couple of hours here and another few minutes there. If I added it all up, I'm probably shooting pool an average of five hours a day, and that's just at home, not counting league and tournaments.
All in all, I'd have to say that buying a table for home is as wise of an investment as I've ever made. Not one day goes by (that I'm at home anyways) that my table goes without being used. It is the source of great pleasure.
