Yes that's the one, but the link you sent shows a very expensive model.
I bought mine (body only) for about 1500,-- (euro's of coarse).
If you have a 550D now, i suppose you don't need the lens. The standard lens for the 550 D won't fit on the full frame cam, but I have some other lenses so I didn't need a new lens.
Hmm I checked on the web and I see the price has already gone up with 100,-- euro's
