I have a WOZLE and absolutely love it. I can't stop playing I've had it for almost a year and it's even more fun now that the software is pretty much done. I like TAF also but I love WOZ. You will be blown away by the construction and technology in WOZ that's for sure.
If you get a WOZ make sure you have the new boards installed. I haven't had a single LED issue since having my game overhauled. People can say whatever about JJP being behind schedule but one thing no one can't ding them on is the way they stand behind their product! They are good people and they'll do whatever it takes to make your game right.
It's also nice to be apart of the JJP community. Jack, Keith, Ted, LTG, and all the JJP crew are involved and accessible all the time.
Good luck with whatever you decide - but I hope you go with the WOZ!
