My mom just retired as a potter in Boulder Colorado and has a very nice Brent slab roller for sale to clear out her studio. I have no idea how much such an item would be worth. The closest new model is $3K. Any ideas how much these things go for used? It's bed is 26” wide X 76” long and 35” high. It's a floor mount unit with the large turn wheel. Closest comp is the Brent 20.
