It's wonderful. I run a UCG Max at home to support both my internet needs and camera storage. Run their other gear in several other SMB environments, including a condo where we're using it for office, building automation, and public area networking along with around 80 cameras. Dead simple to understand.

Crosstalk Solutions, MacTelecom Networks, and Lawrence Systems all do youtube videos on UI's gear and setup - may help give you an idea of the experience before you commit to kicking off your addiction.
