Check out Kartek or k-four for good switches and mounting options. I use k4's switches exclusively in the shop.

 

this is what i made for my truck. i need to make a new one, the holes didnt exactly get lined up properly and are a bit crooked.

 

how's that work with your cupholder redneck? I plan to put my switches on some kind of panel in that area.... Preferably right below the cig lighter, just to the left of yours, but positioned for easy reach like yours
