I am using a black Marware Sport Grip and so far am very happy with it. It does collect a bit of lint compared to a "shiny" case like the Solo, but I find it comes off easy.
I favor it over others because of the amount of coverage not only on the bezel, but the earpiece and home button areas, as well as the dock connector. The molded buttons are nicer than most of the other soft silicone cases I tried.
