I dont know where you are, but there is a trade show in Nashville next week. It is put on by NNEP (National Network of Embroidery Professionals). All of the major machine manufacturers willbe there. There will also be all of the digitizing software companies there. They will demonstrate and prob even allow you to try for yourself.
Most of the floor space will be taken up by vendors who sell the different items to embroider. Check it out here

There is a charge for getting in, but if you call Tajima or one of the other manufacturers, they will probably give you free passes.
