Re: TV on top of horizon?
Syracuse TV risers.

They aren't inexpensive but very well made. He'll even custom-make one, if needed. I had one made when I was using an S2 as a center. Unfortunately, not big enough for the Horizon -- I should have had it made for the Horizon at the time as I figured I'd upgrade one day.
That said, when I got my Horizon, I did make a riser myself.
