Not surprised you’ve had to go through all this. You should try Logaholic Web Analytics! I use it for one of my sites and I must say I am very impressed! It has all the functionalities of Net Tracker and even more features if you want to do sales funnelling, A/B split testing and track conversion to target pages. You can get the trial from here: http://www.logaholic.com/wp/products/
Good luck!

Instead I recommend running Google Analytics or AWStats.

I”m now should start a webtrends setup project . Can you estimate how many hours such a project required ?

Thanks,
