OEM, pads, rotors, sensors from here (
http://e-partssales.com/Merchant2/merchant.mvc?Screen=CTGY&Store_Code=P&Category_Code=98625brakes ) are about $670+shipping.
The nice thing about OEM is that you don't have to worry about inferior quality (ie made in China crap and have no warranty) and should mount with no issues.
No need to replace sensors if you are willing to look after the pads yourself (save some $$

).
Also, how many miles are on the rotors? unless they are too thin (forget the measurement) there shouldn't be a need to replace them.
