Any good Electronic Part store(s) in the Philadelphia area?

Does anybody know the location of a good Philadelphia electronic parts
store. When I was
living in Newark, N.J. I would drive to the Electronic Barn in
Bloomfield, New Jersey.
The store had a large selection of used, electronic equipment and
diverse component level parts catalog.
I am looking for store similar to the Electronic barn that resides in
the Philadelphia area.
