A Substitute For Google Analytics?

I run a lot of sites which I would like to track the hits (conversions etc) but using a hit counters fall short compared to Googles Analytics. Anyone recommend something else. (I'm almost making a lot of money sites and don't want Google knowing they're connected).

Just found http://www.getclicky.com/, Might go with them.. Anyone found something or know of someone else?

I just started using http://piwik.org/ today. it's an open source google analytics's alternative, you need to host it yourself but setup doesn't take more than 5 minutes, and theres plugin support for wordpress. It's very clean and gives you ALOT of information, i can't give you a decent review since i just started using it, but it looks good

I use the old and reliable statcounter
