It depends on what you want. I go every year. There is a guy at the end of the Chocolate field just before you go over the walkway to the Green field. He has tons of stuff.
A few years ago someone here wanted early Chrysler number wrenches and I got the contact info for him. He bought all the wrenches they had. Next year my buddy wanted stuff for his 1929 Chrysler but alas they were all gone.
There are plenty of wrenches scattered in the 9100 flea market spots.
