I love my ASUS RT-N16 running DD-WRT although I have heard from friends
that tomato is superior. With a 480mhz processor, 128mb of ram, and 32mb
of flash its a beastly little residential router with the right software
running on it. I haven't touched it since I set it up other than to
upgrade to the latest DD-WRT. My wife's TV obsession combined with my
torrent traffic has made my life miserable with more than one router
running a proprietary firmware. 

Unfortunately I don't have any numbers as to how much traffic this thing
can actually handle, but I can only assume that it's much higher than
the Linksys models with lower specifications. DD-WRT gives me all the
control I need over my home network, but it certainly wouldn't be enough
for all situations.
