Found nice Stats script for WP....

By far the best I have found - SlimStat.

Works fine in MU mode. It might get a bit heavy on resources if you have a high traffic blog though.

Well, thanks. I'll check it out!

Looks pretty cool. Have you used WP-Piwik? If so, how does it compare?

I kinda like StatPress.
