Billet is a good thing as you can always polish it to a nice shine. However, whichever way you decide to go, I do suggest that you put the new unit on a glass tabletop and make sure it is indeed square. Also, if you decide to go with another chrome unit, I suggest taking 400 grit sandpaper to the mounting surface and using gasket "tack" on both sides of the gasket itself. Been there, done that and 250 miles from my driveway .
