I would personally suggest Linksys as this is built by the same company which build the industry standard Cisco routers.
A lot of the Linksys routers run Linux firmwear and as such can be hacked about to improve the performance and security.

Linksys are the best residential routers around imho and can easily be tweaked for unbeatable performance and features for the price
