I love my glass top and would never go back to the burner type. Mine is ten years old and the top is a small black and whitish grey mix design. Having the mixed color probably is a big plus and it definitely doesn't look it's age.
We use the Cerama Brite that came with it and also the Cerama scraper when needed. I just went to check it and DH was in the kitchen and even he thinks it looks good.
