You might look into Microshift for the triple FD shifter, they are one of the Shimano compatible small guys with slightly lower prices, http://www.microshift.com.tw/product_road.html

The website has the triples listed, and it references which Shimano components their stuff matches up with. Supposed to be fairly good components but not first line as the Shimano stuff is thought of. Of course there is always eBay, just watch what you bid for.
