Really I'm looking for the 2 piston kit with 12 to 13 inch rotors for the front, i think usally retails for $450-$650. And a matching kit for the rear probaly the 11inch kit.
RPM Outlet - $470 front / 230 rear (plus 1 eradispeed using existing calipers) This is a nice, good looking, great performing setup at a reasonable price. One of the Mustang Mags just did an install and write on them in the past month or two and now they are on my wish list. http://www.rpmoutlet.com/musv8baer.htm
