Yeah, sort of. I had a listing 2 hours south of me, a machine head in poor shape in a nice #21 parlor cabinet. The seller wanted 4 or 5 hundred dollars. i watched his ad for weeks and finally reached out about separating the head from the cabinet.
Another week or two of back and forth and I was headed south, coming back $200 lighter with that gorgeous cabinet in my car.
I very much like those trapezoid cabinets. $75 seems a little steep but I'd probably bite. It's a case of a few more bucks than I'd like to spend vs how often do you see one?
