Lost my pinheader so I need to get a new one, would Radio Shack have them? It's kinda hard to find them because I live in the Bahamas, but if Radio Shack doesnt have them, could I salvage one from, say, an old mobo's IDE controller? I have a stack of broken parts in my house, so I guess it's their time to shine, could someone give me an example of where I can find them?

Any electronics store should have them as its a common PCB header or as you said a suitable one could be removed from an old m/board.
