See these recommendations from PilotPTK. I have jumped on the Hobby King Hakko 936 clone which has excellent reviews, is available from US Warehouse, is very cheap, and has tips easily available (cheap on Ebay). As I was on the page reading reviews I got a pop-up that offered it to me for only $15.62!
Wait a minute. Now I see it's on Back-order.
