Best wall bracket for 42"?

[darknite]

Just wondering what you guys use bracket wise? To attach to a new build, so plasterboard hollow walls. 42" LED unit. 11.5Kg in weight. Ideally want swivel and tilt.

Been to my local John Lewis, their suggested bracket is £80+. So a quarter the price of the tv. Seen others online as low as £18.

Just wondering of preference of make? Model?

I like the look of the Ross Neo units.

Just been given a wall mount that says it supports up to 40" TV's but 52Kg in weight. The TV I want to put on it is 42" but only 11.5kg in weight. This would be ok wouldn't it? As long as the VESA is the same size in mm?
