New hardware firewall

So I wanted a new hardware firewall. The old SonicWall SOHO/10 works fine. It's very low maintenance. However, it has only four ports and runs at 10 mbps. I think it's the bottleneck in our network, and since I am getting another computer, I figured it was time to upgrade.

I looked at these hardware firewalls:

• D-Link DIR-130 NetDefend - 8-Port 10/100 VPN Firewall
• Netgear FVS318 10/100 Mbps 8-Port VPN/Firewall Router
• Linksys - RV082 - 8-Port VPN Router with Load Balancing
• WatchGuard - WG50010 - Firebox Edge X10e - 6-Port VPN Firewall
• Netgear - FVX538 - ProSafe 8-Port VPN Firewall

Inexplicably, I selected the one with the worst rating at Amazon.
