A control panel overlay made from either vinyl or heavy printer stock with plastic laminate applied works great. If you look at the "control panels" section of my cabinet site in my signature... you'll see both a cheap vinyl overlay and a printed (and laminated) CPO. Both have been in heavy use for about 3 years now, and they still look fantastic. Many of the original control panels on early machines were metal with a printed vinyl overlay. In arcade settings they got pretty banged up (scratched on graffitti, cigarette burns, etc) but shouldn't be an issue in your home.
I've also seen users here with brushed metal tops, powder coated metal tops, polished wood, home-printed paper covered in polyurethane, painted wood, in addition to various types of plain and printed laminate.
