I live in Wilkes Barre Pa thats near Scranton and we don't have anyone around here besides radioshack aether your best bet is to order samples from oem's example: I just received 8, 8bit shift registers from Texas Instrument. But your only going to be able to get samples from oem's unless your planning on buying a couple hundred thousand pieces other wise you will need to go threw a distributer. Like....

Most of the time i just hunt for junk (Old cell phones, radios, printers, scanners, toys, tv,s etc) i then remove all the parts with a soldering iron or a heat gun and i research all the parts. Then i keep what i want and aether giveaway what i don't or trade.
Hope that helps.
