I just did mine, I got the 9975F set from Atlantic British, std rotors, ferodo pads, and all the hardware to do the job, including seals, for around 270 + shipping, if i recall correctly. Not sure if that is cheap, there are cheaper kits out there, but they did restore my braking to exactly what i thought it should be.
I considered the slotted /dimple option, I know from one of my other cars the braking in reverse is a lot worse, so decided not to go that route.
