You might wanna check with Big Billy Yeadon. He would sleep with the Strong CRB if Colleen would let him.

PS Dan, right now Jon-Don has the Strong machine on sale for over 400.00 off plus it qualifies for free shipping. So why not order one, use it for 29 days and then if it isn't cutting it send it back? Under Jon-Don's 30 day no-questions-asked guarantee they will even pay your shipping costs both way.
How does it qualify for free shipping , when I ordered mine from JonDon I asked about the free shipping and they said I did not get free shipping with this machine.
I agree with Mikey on the quality of these two Cyl. Brush Machines (we distribute both of them).
I can compare the pros and cons of both:
