Sure, I go every second year.
Its a massive show and well worth the effort. I like the buzz.!
As for the "sales" concept, many shows are going that way internationally now, and, even though I am in the business as it were, I have no issue with it. An associate of mine manufactures Life Jackets for the watersport market under various brand names and attends every year as a vendor selling his "own name branded jackets" - he says gets great feed back from the market who ACTUALLY use his product, which alone makes it worth the effort.
