BUFFALO WHR-HP-G300N Wireless-N Router Nfiniti High Power 802.11b/g/n up to 300Mbps/ DD-WRT Open Source support
I currently have the above router connected to RR lightning 40mb/s connection and it has been running great. One good thing about it is DD-WRT comes preinstalled. If you dont need gigabit connectivity on your network which I don't care about since I dont transfer large files between PC's it is great. The wireless range is awesome as well!
Here is a link to look at it on Newegg....
