Bearing in mind that I've never shipped such a thing, I'd want to palletize it on its side, strapped and padded. The arm on top would be off and probably the hand wheel and pulley.
I'd be calling LTL carriers. I *think* FedEx has a freight division.
Remember if you go this way, it'll be moved around by forklift so build blocking and bracing to withstand such handling. When I received my large 441 clone, it was completely set up, standing on a pallet with wooden blocking and bracing, Styrofoam, shrink wrap and every manner of way to keep it safe. So, it's done all the time. Yellow Freight hauled mine from Texas to Maine.
There's a type of pallet called, I believe, a CHEP pallet that's much stronger than a regular pallet. I'd be on the lookout for one. They're used regularly in grocery stores. a quick image search will turn up plenty of pictures. I would avoid a plastic pallet. They're strong but quite slippery.
I bet we'd all be interested in pictures and how this goes for you.
