The folks at Dave Manson reamers are nice to deal with. They had both on the shelf when I ordered mine. Price and shipping were less than I could find for other brands second hand.
Geez.......just spend the $40.00 or so dollars and buy a new one from Manson, or whomever. If someone has a "used" one for sale, you may get it for $30.00. You're trying to save $10.00 and wasting $50.00 in time and energy. A Go gage doesn't retail for $500.00 new........
