I just ordered a set of good rotors from Ed Morad.
$200. Cdn shipped
Not quite sure why I am doing this since I now have a Gen V and probably won't go back.
I will probably do the port and polish mod to the old Gen 3, pop in the replacement coated rotors, reassemble and put back on the shelf as a good back-up spare. Worth more to me as a spare than the $300. I might be able to get for it and the LIM.
