I did mine. Took me 6 hours and 15 minutes. That counts running to the parts store for the pump, and dinner time.
MAKE SURE YOU HAVE AN 18MM SOCKET!!!
Its not the most difficult, just time consuming because of what all needs to come off. The coolant tank, the p/s pump, the engine support, the passenger side motor mount, the little clip that holds the p/s pressure hose, the exhaust manifolt heat shield, all three timing belt covers, the timing belt, the crankshaft pulley, the w/p pulley, the serp belt, the timing belt, the valve cover, and you need to disconnect the lower radiator hose.
I think that covers everything.
Drop me a pm or IM me. Exdelayed on AIM and Yahoo, 25511759 on ICQ.
BTW, I dropped under $90 for all the parts, new coolant, and new p/s fluid (I accidentally dumped mine).
