I think they make an excellent line of routers because most are capable of being flashed with dd-wrt or Tomato. This free aftermarket firmware adds a lot of functionality and stability to the platform. I particularly like having the router perform a double duty of being an OpenVPN server allowing me to connect securely from the road to my home network to bank, shop, etc. securely while at a hotel.

Please google the specific model with 'dd-wrt' or 'tomato' just to make sure that particular router is compatible.
