Hi there. Can't really help, but I'm looking for the same thing I think - a TV stand that attaches to the TV using the wall mount fittings on the back of the TV (that are univeral as far as I am aware).
Ideally the stand would also house all the cables so that they come from the power sockets in the wall, run up the inside of the TV stand column, and then come out and into the back of the TV (so that there are no cables on show).
Edit:
I just found this which is pretty much the sort of thing I'm after... hope it helps:-
