Hi, The shelf our TV sits on is 9" deep, which means the rectangular stand of the UE46F5000 will fit on it. However, I wanted the UE46F5500 model (which comes with the '4-prong feet' stand, unfortunately too deep for my shelf). Are the stands from these two models compatible with either of these two TVs? They both look very similar where they attach to the back. I can pick up a 5000 rectangular stand for about £45 but I need to know I can use it on the 5500. Thanks!
