Well, I got done last night! It was really easy to do and it only took about 15 minutes. I haven't hung the TV on it yet because you need to let the epoxy dry for at least 24 hours but it seems like the ticket. The mount is made by Thule and if you search Thule LCD TV Post it will pop up every where. I got mine slighty used on ebay for 50 bucks. I'll get some pics this weekend and post'em up.
