Can anyone advise me of any good companies in Central Scotland who could mount my new TV to the wall, hiding any cables, etc?

Also any recommendations for good websites for wall mounts? What sort of price should I expect to pay for a 37" wall mount?

anyone?

I got a cheap mount from Ebay for my 42" and it hasn't fallen down yet. It was under £20. You can buy some half round self adhesive trunking if you don't want to channel out the walls.

I've bought quite a few mounts online from RS100 in Glasgow. They've got a good range from budget through to high-end including motorised. I've also found them friendly to deal with and excellent on delivery. They definitely get my recommendation.

I wouldn't be surprised if they could recommend an installer in your area too. Give them a call.
