Need a wifi N repeater/bridge.

[boomhower]

I need a wireless N repeater/bridge. I have done some rearanging and my signal isn't strong enough. I'm at two bars and it doesn't get near the bandwidth for the streaming video I'm trying to get. It has to be wireless N and 5Ghz would be a big bonus. I'm guessing something DD-WRT compatible would be the best route as much as I hate to think about flashing firmwares again. The cheaper the better. I'm partial to Linksys but the Netgear WNDR3300 are available for ~$50. The host router is a Linksys E4200 if it makes any difference. Suggestions?
