I am so glad to see this posting today. I recently sold my HV Designer I with all (and I repeat, all) the stuff that came with it for $750, and the lady is so pleased 'til she is dancing all over Macon County. And I, too, and dancing all over Macon County because she didn't give me a hard time about what I was asking for it. I hate selling anything.
When I first bought this machine, used, I asked a few questions about it, and several of you PMed me trying to help, but I am such a dunce with the HV that I just gave up. I got it to sew a beautiful straight stitch, and with the help of a local friend, made a couple of pretty embroidered pieces, but with all the frustration of not being able to mess with it by myself, I just let it set and three or four years have gone by; so I just decided to go ahead and let someone else have it who might be able to use it.
