I'm considering buying one, but I'd like to hear from someone who's used one. I'm interested in it's ability to cut rosette channels and truss rod pockets, but what others uses does it have? Does the Porter Cable setup come ready to use or do you have to buy accessories for circle cutting? I seem to remember that there was a restriction on the minimum size circle, maybe that's been overecome or I could be thinking of a different base.

Thanks in advance.
