IMO, having went last year it's both good and just not that good.
It was cool to speak with various techs from companies you are accustomed to seeing online. Ecotech, coralvue, dr Tim's, etc. Last year the guys from tanked were therez so that was a neat novelty.
To actually buy stuff is less than something to be exciting for. I think the prices are in fact higher than what most are used to, simply because A. They charge the vendors a ton of money to be there, and B. Because of its close proximity to Manhattan, the feeling must be big spenders attend. You won't see the usual basement frag guys there, more like the big names that travel a good distance to sell there. Most would think they are there to get there name out, but prices dictate otherwise.
I go to many sorts of shows, and I always ask about pricing. I feel some guys start high to give them some room to come down. Doesn't hurt to ask.
