Brent Model 16 Adaptive Pottery Wheel

Looking to find a good Brent Model 16 Pottery Wheel in good condition. Father-in-law is a retired high school art teacher with heavy focus on pottery. He has recently became injuried with no use of legs, and looking to add an adaptive wheel to his in home pottery studio to continue his love of pottery. Willing to pay decent price and travel the midwest to pick up. Open to suggestions on where to find or who may have. Would prefer to not have to buy brand new.
