It has about 10k miles on it and still plenty of pad life left. It grips great and doesn't slip. It's got a little rust on it, but that's normal... it's made of steel, and doesn't affect performance.
The price of a new CM stage 4 is $795, I'm selling my used on for $300 SHIPPED obo. It's ready to ship. PayPal only.
Sorry I don't have pics... my camera's been broken for awhile now.
