Man, I was WAY off . . .
I just checked Fastlane, and it appears my memory isn't what it used to be. The price for FRONT calipers is $80 not $60 (sorry).
The REAR calipers are $130 (ouch) for a rebuilt ATE part.
The rebuild kits are only $15 though. My only problem with rebuilding it yourself is that you might get it apart and find that you need to replace the whole caliper. Then you have the car in pieces, and you have to wait for the part.
Just my 2 cents (arguably worth that).
