The 4x4 rotors do not appear to have any machine work done to them, except for the 3-drilled and taped holes. As I do not know what comes with the Buffalo kit, I cannot comment on it. But an adapter plate is required to bolt through to the rotor. If this plate is not included with the Buffalo kit, you are right in that there would not be any savings.
The three drilled and taped holes in the rotors are matched to the three rivit holes in the stock hubs. One of the problems I have had with the CPP kit is that the adapter plate counter sunk holes did not match the holes in the rotor. I had to fill them with weld and re-drill and counter sink them. This process alone has taken me about 2 hours per plate.
The other problem I had was the caliper brackets were not bent correctly. After spending an hour or so figuring and measuring to see where everything needed to be, it took me a couple of hours of bending and tweeking to get everything offset correctly and the calipers in the same plane with the rotors.
