Let me try this again.
I believe the used pair of rotors to be worth $400-$500 + pads + shipping.
Dealer is just over $1,000 each for the front and just over $800 each for the rear, so $3600 for the set. They can be had with some shopping for $2800 for a set of 4.
New from VPA they are $1250 for a pair and $2500 for a set of 4 for the OEM, definitely a good price. These are the bronze hat version.
Some other place which I have never bought from nor am I pushing sells the black hat Stoptech version for $800/pair & $1600 for a set of 4. (which are not the exact same as the ones VPA offers)
The replacement rotors/rings (that work on either the bronze or black hat) can be had for $205 each on that one bidding website that everyone hates to sell but loves to buy.
I hope this post didn't break any rules.
