SedoPro will give you decent unique vs. visitor stats, etc., but the basic stats page is very limited. If you forward the domain through a hosted page elsewhere, keeping track of stats on that page gives you much more information about referrer and search terms that took visitors to your page, which allows you to target ads much better.
I also like the basic reports on 1plus.net 's parking service as it breaks it down daily and on unique IP's vs. visits, which allows you to filter out spiders, determine country origin of visitors, etc.
