I know that opinions on the show vary, but I've always found it more than worth the ticket price if only for the masterclasses and mini-performances by the big names. This year there were so many I hardly had time to have a good look at the stands and meet up with other BCers for more than a few minutes!
Bass stars aside, I like the opportunity to GAS, see new gear, collect info about what I might need in the future, and play or test gear (although that's the less satisfactory aspect of the show, given the noise and the crowds).
I also believe that the big companies would one by one desert the show if we didn't support it. Some of the big names were notable for their absence this year, and the only way to attract them back is to make the show a big deal, go there [i]en masse[/i] and make them feel they're missing out.
As for being an exhibitor there, hopefully some of those BCers who were there last March will see this and give you their opinion.
