I can't say anything for Fingbox, but I have been pleasantly surprised with the Firewalla. It is kind of difficult to understand if a lot of the alerts are actually malicious or if they are normal activity, but that said, it does give some insight for not a lot of money. Be careful though, Firewalla limits the bandwidth of your network, so if you need a lot of speed, I would go with the Blue not the Red.
