Web stats that track visitors

I am working on a site hosted at DH that needs more/different information than the Analog stats reports provide - specfiically # of visitors. I don’t feel proficient enough in the server environment to install software on the server.

Are there reliable services out there that will generate reports? We’ve tried OneStatPro - their #s were way off what we were getting at our last provider and they didn’t respond to repeated email inquiries. Urchin On Demand is the opposite extreme at $200 a month but with great support. $20-$50 a month would be ideal.

Thoughts appreciated,
