It's amazing how much snake oil there is out there on the internet with respect to network security. Whenever you're looking a product like this, don't buy the hype. Just break it down, piece by piece, and figure out what they're saying the device can do. In this case, it looks like any Linksys Cable/DSL router could do exactly the same thing - and more (you can configure it!).
I'm not exactly sure about guides for the whole "setting up a computer to act as your own router", but if you are really interested (though I'll be the first to say it can be a large effort), the best way to do it is get a computer, install OpenBSD on it (the FAQs & install guide on their website is amazing) and just start messing around.
