i know of several on the board that build frames, myself included. IMO, and for the money, I would buy NRS stock, and a mess of low pro's, and start laying it out. you could easily have a 5 bay frame, or six depending on your set up. Low pro's are easy to work with, and pretty darn solid. if you don't have a chop saw, you can even buy a junker at a pawn shop. with some basic measurments you could have a frame put together in a few hours., for a heck of a lot cheaper than buying a fabricated frame.
I built a frame for a guy with a avon pro, it was pretty trick, double rail, 6061 t-6 rails, 6061-t-6 d-plate, 1/4 inch, 5 bay, powdercoat, and it was 1900.00, just to give you an idea.
