I snapped a belt at 25,000 miles and just passed 50,000 miles overall with my SC kit and doing all the above including the belt again (already has cracks). After this change over I will be dropping my interval down to 25-30k miles instead. Overall the materials will run you $250-300 and can mostly be done yourself or a good shop can do it in a couple hours tops.
