I spose what I was trying to say, which has been echoed in the other posts above is that you can't expect to make big bucks, if any, out of an expo alone.  It is really a bit of a show and shine and an attempt to get everyone together in the same spot and a chance to get newbies involved as well.

It is a shame there is way too much politics in this industry but I can't see that changing anytime soon.

In lieu of expo, I'd love to see a pinball market get up and running somewhere, no glitz and glamour just a community hall that could be anywhere or travel around, sort of like the computer fairs, and have a place to either display your stuff, offer it for sale, run a tournament or do whatever you would like to do with it.
