Its great that the one radio club in Eastern PA, Delaware Valley Historical Radio Club has this meet.
These guys are great and I always seem to have something somebody wants but I COULD easily leave with a with a full truckload! Few of us need to go that overboard, twice a year no less.
If you search ebay,CL or anywhere else,
pretty discouraging for us tech-collectors when you have to deal with ignorance of values in particluar
I packed a few small things and a '76 Zenith Space Command color set in my truck and came home with a nice Grundig and Blaupunkt table radio, a 1946 Sparton 7AM46 Console (to match a 7-36 I sound at SA thrift store),a Westinghouse H648 table set and a Fisher 101R AM-FM Tuner.
I just started on another bargain Grundig found last time there.
