I bought a UM110M - Ultimate Mounts Twin Arm Cantilever Bracket for £49.99
32"-60" TVs and a PAVS 3S - Premier Mounts 3 Shelf AV Support System as a cable tidy primarily, but also useful shelf. Both arrived fast and were well packaged.
The bracket needs 2 people to put it up, directions are good enough but it would be helpful if they included a printed template for drilling into the wall - I made my own. Bracket itself is great, easy to move but rigid to hold position, and importantly easy to adjust to get the TV perfectly level.
The cable tidy/shelving is good. I am only using 1 shelf as I already have a stand but I may add another shelf later. I use the shelf for the centre speaker, I was concerned about vibrations, but none noticed, it is really solid.
Overall, really pleased
