If you can handle crowds, it is a blast, er bzzzzzzzzt, brrrrrrrrrrraaaaatt.

Yes, they have flamethrowers...
Went with a group of friends this spring and it was crowded but quite worthwhile. As Northgunner alludes, you will see stuff there that you won't likely see anywhere else. And the stuff ain't sittin idle. It's burpin out projos!!!!
Next time I go, I am hoping to see the Sat night shoot. The videos should give you an idea of what to expect. It will add a whole new visual candy dimension.
As far as a table goes, that will be tough. As I understand, getting space is $$ and with a waiting list, the owners can pick and choose who they want. Most folks come to by some ammo, parts, ammo, FA parts, barrels, ammo, FA guns and a little more ammo. Those guys go thru crates of the stuff. Incredible. Some of those guys appear to shoot more in one weekend than an active shooter would go thru in a lifetime! No kidding!!
Most of the tables are full of serious gun goodies with very few 'junk/fleamarket' grade items. Even the larger name companies have a relatively small space that is just CRAMMED with ammo for sale, mostly milsurp, with some new Russian stuff (Wolf). So, I would think the owners would be looking for someone with gun goodies to sell.
Maybe the way to get into the show would be to make a deal with someone who already has a table?
