Network Scanning Software ?

[Juic3]

Hi, I'm looking for a decent program to scan my network, better if its free but if its good enough I'll pay. I want to be able to know whats in my network even if some hosts are using some kind of fw software.

Ive tried Retina and its really good, so Im basically looking for opinions on other maybe better software .
