Absolutely a home needs a hardware firewall. I would make the claim a home needs a UTM/NGFW in these days of blended devices and blended threats!
Forget about the 60B, it's legacy and overall has very poor hardware. Also you won't be able to license it for UTM features but would still be able to use it as a NAT Firewall on your network. However once again, the 60B will run older, less secure firmware. In the case of Fortinet it is absolutely crucial to run the 5.2 series firmware at the minimum.
The lowest Fortinet I would purchase would be a 60C. I currently have a 200B in my home, which was around $5000.00 or so. You can pick them up on Ebay for about $250 or so. The 200B is very very powerful and can run the latest 5.2X firmware. As a NAT firewall it's astoundingly powerful. You can also run it unlicensed but still utilize the IPS feature which defaults to about 6000 signatures which is actually pretty decent. The other benefits of running a Fortinet (Licensed or otherwise), you can setup VPN's very easily for your devices. You can also setup VLANS and some very nice policies on it. Far far above what any consumer junk router can even approach. Note: I am a Fortinet NSE8 Engineer, and I work on Fortinet devices for a living as a Senior IT Security Engineer.
Going forward, most homes will almost essentially need a strong firewall and/or UTM/NGFW in the future! Norton Core Security, Bit Defender Box, CUJO, and about a dozen other products are here or coming out soon with UTM-Like features for the home. ASUS already bundles Trend Micro (Gateway) with their routers.
Here's my rack at home with the 200B shown. I also run 6 VLANS, 3 223C FortiAP's. I run WIDS, RogueAP Detection, IPS, etc.
So, recently i've wanted to get rid of all my software firewalls including windows firewall, and Emsisoft firewall which has been implemented into Emsisoft Internet Security. The main reasons for this is that even with customised filters, everything was being scanned and caused massive CPU Usage, I have a gaming PC and having High CPU usage isn't optimal for everyday gamers. I am not looking for another software firewall but alternatively a hardware firewall. I was looking for something with a basic UI, that isn't that expensive.
Some people may be thinking by now, this guy is crazy! Why would he need a firewall for home? Well the amount of times a partly non intrusive firewall will save me is countless.
I was looking at the following
Cisco PIX 501 Firewall Bundle, PIX-501-BUN-K9-Newegg.com
New in Box Fortinet FortiWifi-60B VPN Firewall Security Appliance fwf-60b-Newegg.com
I am literally uneducated in terms of hardware firewalls and most networking related hardware apart from routers and such basic things.
