Deb, will you be moving your machine yourself, or having movers do it? We moved last year, but less than an hour away, and we moved my machine ourselves. I wrapped the rails in a lot of bubble wrap, as well as the table. The trickiest part was getting everything in my van, and it took us more than one trip. The guy who came out to estimate the moving job looked relieved when I told him we would be moving Emmeline ourselves.
Sorry I don't have any advice about using movers. If you are on Facebook, you may want to ask this question there, in the We Love APQS group.
