If you're looking for a good, EASY TO USE, FREE stats program, consider StatCounter. The only drawback I saw to StatCounter was the limit of 100 stats on logs. Meaning you could only view 100 stats at a time before you lost some.
Now they've upped that to 500 for FREE, making it one of the best (and easiest) stats programs I've ever used. And StatCounter is REAL TIME stats, not like that crappy program MyBlogLog uses. They only give you TEN stats a day and it's a day behind. Pfft.
