Eddie is correct - even the low end hotels in York will be $100 after taxes. Lowest price I've seen is low to mid $80s per night.
I stay at the Best Western because it is attached to the Quaker Steak and Lube where we have dinner Thursday night so I don't have to drive if I have too much fun.
If you are fine with driving 15-20 miles to and from the fairgrounds you can find better deals - search Hanover, etc.
By now, most of the better hotels are already booked but don't despair. Up until 3 years ago I just waited until the night before and got good deals on Priceline. It all depends on what your preferences are.
