I am really not sure why all those web log analyzers are so costly. In the past, I use to use webtrend which was great until they gave up on the software version and went only with the web edition and that was really pricey.. Now they brought back the software version but it is still not that cheap.
Urchin too. It is just too costly for the software and the monthly one is even more rediculous. But seriously if Urchin is making good money with what they are doing then Google is in for a good investment. To the shareholders, what is important is profits. I guess they are swinging with the other crowd.
I use Urchin because it is available but don't really find it that great to cost as much as it did.
