I'd like to buy a Compu-Dobby II. I could buy it for cash, or I have a mechanical dobby with many bars that I could trade -- plus many dollars, of course.

If you are selling an AVL loom with a Compu-Dobby II, you might find that a potential buyer who is anxious about computers would prefer a mechanical dobby. In that case, let me know as the trade plus dollars might work out well for both of us.
