Software for Auto-Generating a Site Map: Please recommend!

[PTC4SEO]

I have a new client whose site has 20,000 pages in Google's index.  I'm looking for software that can scan the website and auto-generate me a sitemap. Can anyone make a software recommendation? It's important that the site map differentiates between levels and shows site architecture / hierarchy.

Thanks Wissam!

I did some searching and downloaded Site Map Pro. It is in process right now (estimated 7 - 10 hours). I will try your suggestion as well and compare the two.

Your response is greatly appreciated!
