I just got my Ef-S 10-22 just this month and it works like charm. Perfect when there's not enough room to move to take pics of groups in a party.
I have to suggest on getting the Ef 70-200 f2.8. Less lens change = less dust on the camera/lens. If you're still afraid it may stick out, have you considered Lenscoats? You can cover your 70-200 with black if you want to. I'll be getting one for my Ef 24-70 2.8 cause it looks cooler in digital camo []
