Compete.com and quantcast.com are the only free alternatives that are closer to reality. I have no idea how accurate Compete.com is but Quantcast is extremely accurate for sites that have added their tracking code. Basically, Quantcast is like open Google Analytics. I've added Quantcast tracking to our site recently and their estimates are close to our logs (once you discount for bots etc).
What do you think about Compete.com?
