my current one (linksy WRT120N router) does not work with my broadband modem as it causes the internet to go out every hour. So I need another one so I can make use of sony's PSN service. So if you do know a good gaming one besides linksy, let me know.
D-link makes a pretty good Routers according to Amazon reviews. But, it is expensive...

If you don't mind restarting your router every few days by unpugging it, and replugging it from the wall, You can try TRENDnet 54Mbps Wireless G Broadband Router TEW-432BRP (Blue): http://www.amazon.com/dp/B000BI1XNE?tag=johsgamsto-20&camp=0&creative=0&linkCode=as1&creativeASIN=B000BI1XNE&adid=1J5MGTWDBX71H8RZ7JDW
It is the router which I am using when I don't have access (someone is sleeping in the computer room) to the wired internet computers. It works pretty good, but the wifi drops every 1-2 days, but other then that. It has been a great router for using with my laptop which is connected wirelessly to the internet since the wifi signal reaches the third floor of my house.
Get a Netgear WGR614. In my opinion it's the best wifi router around. I don't own one, but my friend says that it's great and the signal is pretty strong too.
