Rick, Welcome to the site, great to have you here. We do have a great group of BBQers here and lots of great discussions & events.
As for the Mop, I would suggest checking out BBQ Island, they carry a number of different mops there and if they don't have what you are looking for, they will order it in.
Look forward to seeing you online here more and meeting you out at some of our great upcoming events.
WELCOME!!
Mike
