It was the first show I've been to of this type. They bill themselves as "the largest show of it's type in the world", but it wasn't that huge. I don't know if you've been to pheasant run -- it's big, but it's not like McCormick center big.
There were probably 30 arcade machines (about half were multi-play machines -- forgot which vendor it was though), and I would say about 30 pins. I saw one Addams family, one ST:TNG, and a brand new Star Wars machine with a floating video display overlaid on a section of the playfield. That was nice, but it was about $6K. Pins and vids ranged from $600-$6000 in general.
Tons of other stuff: 45's, plenty of fridges, nostalgia items (coke signs and whatnot), street signs, other crap, etc.
I didn't buy anything -- I'm planning on buying a pin someday, and that's mostly why I went -- but I couldn't pull the trigger.
