The 3500 will do, BUT you'll need the GS medium cage version and NOT the SS one. Chain reaction and Wiggle have these at a much lower price than the one you linked on ebay.

If its the GS version Medium Cage (there is not really a long cage on road bikes) it won't fit the new, 3500 will as will almost any M.T.B. RD the newer Tiagra and 105.
I can get 28th out of my old RD3300
