How about the Check Point Safe@Office? (Score 1)

Safe@Office - a wired and wireless security appliance, with DMZ/VLAN capabilities, secure wireless (seperated from the LAN which can be good for you!) as well as additional services like anti-virus and such. Also has remote access capabilites and runs on Check Point firewall - if security is important to you. Check it out on http://www.safeatoffice.com/ If you get mixed up, try speaking to one of the representitives in a chat - they are quite helpful. They're a tad expensive, but it may save you having to manage two appliances or worse, two modems.
