Any Project Manager or aspiring Project Manager out there? 

If that is you, what tool do you use?  I heard Primavera is the best, I have never used it, but MS Project is supposedly most widely used in business, probably because it is cheaper.

I have been looking for Microsoft Project 2007, preferably a free download.  If you know of a website where I can get it from, please let me know.   I know I am not only bad ass, but cheap ass too, what can I say?

Thanks.
