I was at the 2010 Schomberg show. The host group was very gracious and the models on display were high quality. Note it is a pretty small show. There were a couple of good vendors.
The town is actually pretty quaint and its not far from Toronto and Niagara Falls. I stayed at a B&B not too far away and it was horrible (can't remember the name, must have blocked it out of my memory!). I'd recommend one of the hotels in nearby towns.
All in all a nice show.
