Learning Fortinet

I was thinking about learning on how to configure Fortinate Firewalls and I was thinking about buying a small home firewall to play with. The purpose is to learn syntax and whatever I need to know. My question is do the small home firewalls use the same UI as the enterprise editions? My line of thinking is that if I learn it on a small piece of equipment, it'll carry over to the enterprise editions.

Your thoughts or suggestions?
