I recently came across a few sites actually. Poker Prophecy is a downladable poker software that gives you an idea of how good your oponent is. I prefer www.tournamentreporter.com it tracks your entire poker tournament playing history and gives you insight into your play. It also ranks you against your oponents to see how you stack up
I actually just read this post and checked it out. I looked up my player H Rolla and was surpirsed to see it there and my J ranking. thanks for the site
