Have tried the Groovy Boards, as HQ calls them. Too expensive for me and then I'd have to store the boards when not in use ... and of course, I'd want two of each so that it would be easier to assemble the pieces in a consistent manner.
That being said, a friend of mine bought the HQ stylus and her hubby made her boards using his router and it worked great. He had the talent and they had the room to store them.
