Ebay sucks! I won a bid for pi heads and intake manifold for 460 shipped and the dooche bag sent me a message saying that he is going to be selling it to a friend for 500 and that if anything else came up he would send me a message. WTF!!!

I really don't wanna deal with ebay people anymore but i dont want to spend a small fortune on a pi head swap. Is there any known good ways of finding what i need local?
