Welcome to the Quilting Board!
Hope you find one. I have a 15 and a clone that both need cleaning and fixing, as well as the 15 that came in the straight leg treadle base. I haven't gotten to sew with any of them yet....too much sewing to get done before Christmas!!
So are you thinking this machine on CL is not one to look at? I'll go check out shopgoodwill. Been watching CL & Ebay. Will see what's "new" at SGW.
