Anyone have any experience with a good model or company that makes those carpet (or other) dash covers to put over a dash that is starting to crack from the sun.

I don't want it too look "cheesier" than it sounds to have a dash cover in the first place.....I don't want corners curling up and stuff. Any web sites would be appreciated....also if you have any information on the ones to avoid If you do not know any good ones. I would appreciate that as well.
