Where to find good trains

Like I said in my last post I just started collecting. I have seen alot of rare trains so I know whats a good deal or not. When I do try to find a good train it will say that its like 22 dollars but then the shipping is like 70 dollars. Does any know a good place (Besides Ebay,Amazon,and Yahoo Auctions) To find good trains? I am currently looking for the Galaxy Express 999.
