Vuln scanner software choices

[Tblinux <TBLinux () covad net>]

I know that most if not all of you use or have used Nessus at some 
point. I've been following the thread. Now that it appears that Nessus 
is seriously ratcheting down support for independent consultants and 
corporate / gov't users without a registered and paid for license what 
scanning software are you considering? Has anyone done a *complete* 
comparison of all of the scanning software out there and made a choice 
based on the findings? If so what was it?

I work for a fairly large company and the contract negotiations with 
Tenable are going poorly and the company I work for is looking at the 
options.

Any input would be greatly appreciated!!!!
