GFI LanGuard is a network security and vulnerability scanner designed to help with patch management, network and software audits, and vulnerability assessments. The price is based on the number of IP addresses you wish to scan. A free trial version (up to 5 IP addresses) is available.

Cons: Extremely slow, auto-uninstall of programs does not work. Missing patched detection is hit or miss. If you are not logging in as someone who has local admin on every machine on the network, you must create a local user that is a local admin and run using alternate credentials. Very annoying if you want non-admin users to run scans.
Pros: Built-in reporting is useful, and makes color graphs for the PHB.
This tool is easy to use, fairly comprehensive in scope, and helps create great reports. Price isn't that bad either.
