I think the Cleveland show has a pretty good mix of boats. Here is a link that tells about it. http://www.lemta.com/boatshows/midamerica/
National Marine usually has the biggest performance boat display with Baja,Cigarette,Fountain,Hustler, and Outerlimits. http://www.nationalmarine.com/
Costal Marine Sells Wellcraft Scarab http://www.coastalmarine.com/
Monroeville Marine sells Formula
Franks Marine sells Warlock
J&J sells Powerquest
There are usually some others like Eliminator.
They have the usual Put in Bay display set up for some refreshments.
If you get bored at the show Head for the flats or Brookpark road I'm sure you can find some excitement there.
