I haven't used them in my house, but we have some smaller ones around our office. They definitely have a more modern. sleek look, if that is what you are going for.
Are you talking about foil prints? If so, my husband got me one of the Chicago street map (we live in Chicago) for Christmas in gold foil and I love it!
The foil ones are metallic - i.e. not aluminum. I've used Aluminyze in the past James, they're great. They do a sample pack on their site for you to check them out and my clients have never had any compaints with their work; they cater to pros and consumers. They do discounts regualrly also with 40% off a lot of the time. Check out their site (http://aluminyze.com/) and give them a try. All the best.
