FWIW, I also have a cocktail, and I used a piece of glass ~900x620mm, 50mm radius corners, polished edge, 6mm grey. AU$100, but 3 other prices at ~AU$150, and some at 280/300.
The tinting is great, it hides the monitor when it's not on and makes the games with a black background look fantastic.
PS, metric is awesome.
