I've had it for a couple days now, but wanted to actually test it before I decided to keep it. For the price, I could not pass it up. It being a Wireless N router, and DD-WRT supported. I figured I couldn't go wrong. Glad to say, I haven't! If it weren't for DD-WRT, I would have already sent the router back, even with it being so cheap. I'm actually buying 5 more, and using them as presents, preloaded with DD-WRT of course.
I think the Asus RT-N16 is a really good wireless N router.
533Mhz processor, 128MB RAM, 32MB ROM, and you can run custom firmware (Tomato, DD-WRT) on it.
