What is best tool to examine web logs (Apache)

I  am using ipowerweb's built in awstat program to view web site data.
However It takes a while to view the last 6 months of data.

Basically I would like to view any number of months stats at a time, instead
of limited to one month.
Then I would copy and paste into MS Excel all the search phrases, words,
most popular pages (instead of doing them all 12 times) etc.

Any suggestions?

thanks.
