i set one up for a companies small lan (about 15 nodes) and have not expereinced any problems as of yet. i also set it up to email me the logs so i can remotely monitor any compromises in their security. they are not paying me to do this, but i do it anyways. to my knowledge, there has not been any sever security flaws discovered. linksys seems to be fine for the average home user and lan, but for small companies that have an extra dollar to spend, i would go with sonicwall.
