Starmicro has a p4 2.66 533 fsb cpu for only $10 plus shipping. The product id number is 1020. Don't try the prescott version unless you want to use a better heatsink. Your board will only work with 533 fsb cpus; 800 requires a different board. If it doesn't work, you can sell it on craigslist for free.
