I have an ASUS RT-N16 (acting as router-only) and a Netgear WNDR3700 (acting as AP-only).
I found the wireless performance on the N16 to be pretty lacking, but it runs Tomato beautifully which I love. The DD-WRT team has become far too arrogant for my liking and basically refuse to fix things it seems. As such, I ended up reverting the WNDR3700 to stock and use it as my AP only. I had originally ran it as my AP+Router (like any normal person would) but DD-WRT's QoS is lacking. Likewise, Netgear's firmware is far too clunky and slow for me to rely upon it.
No date/price yet for it, but this looks like to be the champion of consumer routers:
