There are two types of web analytics technologies: log analysis and page embedding. As you are providing statistics for 200 web sites (clients), you want to stick with a log analysis solution. As the two big boys (Microsoft and Google) are going to be providing FREE web analytics based on page embedding, many of the companies currently in the web analytics game will go out of business as half their market will be lost. That said, stick with a company that is big and has not put too many eggs in the hosted service (page embedding) basket side of things. My personal suggestion would be to stick with LiveStats.XSP v8.03 (the last release). Even though support will expire, your installation will still be good forever. Some of the info in it will become outdated but... All in all, it's a gamble either way. You're dealing with a company that has been bought out, the next one you go with may fold. Good luck!
