I decided to give it a try, and after 4-days I must say it's been an easy purchase. The install went without a hitch and OP was even smart enough to sense my KIS install and tailor itself based on active KIS components. It's running in auto-learn now and OP has generated two popups, both related to entertainment mode for games.
I've experienced no performance issues, failures or compatibility problems so far. I tend to prefer a multi-layered approach to security, considering the ever-evolving nature of today's threats and sheer ferocity of the environment.
Edit: I'm also running a Belkin wireless 108G MIMO router for good measure.
