At the show you will find booths manned by both manufactureres and distributors.
The Manufactureres are great for learing the products and comparing products, but most will not sell direct to the public and will inform you of their distrubutor network in your area.
Other booths are distributor booths and they will sell to you at the show. Many offer "Boat Show Pricing." Lots of goodies can be found at the show; blocks, clothing, electronics, and etc... Not sure if you will walk out the door with a furler, but you certainly will be able to make contact with several sources and you will be able to ask lots of questions.
