Use ebay. I've met a few local people that have/can get parts through ebay. I live on Long Island, and have seen a few people in Brooklyn. Actually I was planning on getting some parts from someone in Brooklyn that I bought some pcb's from, but can't seem to get in touch with him. I even found 2 empty cabs on ebay for $10 each! They turned out to be 10 BLOCKS FROM MY HOUSE! You can email with out bidding.
