I can't give you a direct link right now because I can't access the armory from work, but look up 'brik' on the stormreaver server. That's my paladin, and he has tanked icc and toc 25 no problems - all of his gear save I think his shield is straight from heroics/badges/crafted junk because I can't get anything to drop for him to save my life.

Also, buy the key from frost badges first - that trinket is amazing for tanks.
