Best Analytics for Comparitive Shopping Engine?

[ShopFor]

We've been looking for something more powerful than the simple Awstats we're using right now without getting too crazy on the price.
The site is a newly launched shopping engine with about 300K pages at this time.

Most of the Analytics software is understandably directed at straight eCommerce sites. We have some fairly unique requirements and we've been unable to sort out the best package for us yet based upon the information available in the very informative string at the top of this Forum or though support from the individual products.

Primary requirements for us are:

1) Daily web log analysis
2) Daily Search Phrase tracking
3) Advanced user navigation tracking to study all the habits and trends of our users.

We're OK with the ClickTracks package, although it was clearly designed for an eTailer. We're not ready to jump all the way to the cost of a WebTrends at this time. Does anyone have anything they might add to the closed string above to help us to make a decision?

Analysing a website should be made flexible to other kind of site apart from the usual e-commerce sites..i have a similar problem in deciding on the best analytic tool to use..clicktrack can be helpful but i still need more insights like, which particular user clicked on a particular link or page? so please any idea on a more flexible tool?
