Check out AutoZone.com. They had one shipped to me in 3 days and I think was $168, and also got $30 of that back for the core. Free shipping, and they threw in a $15 gift card since my order was over $100. Granted it was remanufactured, but has a lifetime warranty. Worked great. No need to pull the pulley off. It comes with it. Just need to steal the reservoir off the old pump.
*edit* Just realized you have a protege. Not sure if that pump is the same as the MS6 or not.
