The calipers are the expensive bit. You need to really stomp on the brakes and get them really heated up to burn off moisture and prevent rust and them seizing up. Changing out the pads is the easy bit.

Sorry to sound like a kill-joy but I had to replace the calipers on my SC and it was a major PITA, whereas if I'd given them some death in heavy braking situations instead of my usually mamby pampy braking they would have been OK.
