...And after taking a quick gander it seems that not only have I worn out my brake pads completely but even started to warp the rotors.

I've priced a couple of mechanics and the best quote I've got is $375 for front and back brakepad replacement plus rotors. Anyone know whether this is a good price or should I fork out a few extra bucks and upgrade to some better brakes?
Any help would be appreciated.
Danke, Greg.
