speaker grill material

Hello,

I am looking to change the colour of my grill material more to my wife's liking. I need a silver grey colour: Does anyone have any experience in such things and can offer a good mail order place to buy? I looked around the web a bit and found a couple, but prices were anywhere from 9usd-70usd a yard and not that I do not trust mail order via internet, I do not trust mail order via internet.

Thanks
