I've seen his work and it looks really good, but I'm having to do this on a shoestring budget (read broke). I believe I can do this with the junk parts I have without having to spend a dime... of close to it. I know putting a Polaroid back is how everyone else has done it, but I'm thinking of making the internals packfilm, and simply increasing the depth of the back, thereby allowing the use of the full camera back that's on the camera, just raised to make room for the packfilm case.
