If you only surf online then, in my opinion, you don't really need a hardware firewall, a software one being more than enough with a proper antivirus next to it.

As for hardware firewalls, the only one I've had more than just simple experience with was one of Arkoon's (french company, but they are supposed to sell for international customers too). It was configurable in-depth, but you needed to know what you were doing.
