A Good Robust External Stat Program?
 

I have AddFreeStats which provides comprehensive info. I also have a custom exit link tracking script installed to monitor affiliate and website feeds outgoing clicks.

I need an external program that will monitor these external clicks. AFS Adsense is down most of the time, and I have a heavy server load issue that will require me to remove my custom script.

What's out there that will monitor these exit links? My site averages about 1-1.5 miliion PV a week, so I need a robust, accurate program.

Any valid suggestions?

Thanks for your thoughts.
