Keep in mind that AdTrackZ and ProAnalyzer are scripts, while the others are third party hosted solutions.
Personally I prefer a one time installation as opposed to monthly subscription services, but others prefer the point and click simplicity of not hosting their own solutions.
I'd suggest checking them out, narrowing it down to the few that look appropriate to your situation and then emailing any questions you have to each provider.
For me, customer support and responsiveness is a major factor when I'm weighing options.
1) The tracking script or service must include a way to capture the event and amount of a sale for evaluating conversion and ROI.
2) Ideally, the script or service should be able to handle visitors arriving without a special URL, i.e., it would be interesting to compare the peformance of Google searchers to MSN searchers, or those arriving from links on other sites. These "free" searchers would arrive on the site at the home page or standard content page - no tracking page or tracking query string would be possible.
3) Working on either Windows or UNIX servers would be a plus.
I have a page on my site that gathers all the stats I care about based on recent data. The only downside is it doesn't track trends, but that could be added with a little more work. Of course I'm not bothering with pretty graphs..
Sometimes, I go through all pageviews of a visitor (if I'm really interested about a particular case).
Also, no graphs. Just a bunch of sql queries from a shell script with the output to a text file.
It proves to be most flexible, since I cat get stats with respect to any combination of parameters.
The most complicated one is visitor pattern stats.
The tracking and analysis itself is simple, but I could not find an easy way to display it.
