Looks like a decent deal but it only gets 3 'stars' on newegg. I try to only buy 4 star or better products.
Most routers suck without custom firmware. From all accounts this router seems to be good once you get one of the open source firmwares on it.
I'm kind of jealous. Got the 3600 a few weeks ago and now this one is on sale. I don't even have any 5ghz devices except for my laptop but it's always good to be future proof.
