I think he's just saying that because he doesnt want to deal with having it resurfaced and it would be easier to charge you for new parts.
Before you get the King Cobra, look at the FMS Heavy Duty. Its 20 bones cheaper and has stronger internals. The HD is 5 percent harder to push down though. KillerCanary recommended it to me, he ran it before he got all fancy shmancy with some composite custom thing-a-majigger.
