No.
But, I have two pennies to rub together, since I have a Kestell. Some points:
--60" is probably a little TOO big. Think about it: you should be able to rake in pots without having to get up and reach after every hand. 54" (which i have) is nice.
--I'm totally in the round camp, and the company's web page makes good points about it's virtues (though they make too much about octogons, its not a big diff).
--$600 seems a bit much. A similarly sized Kestell is $400, though if portability is a concern, this looks ingenious.
Good luck
