So.. what's the newest, toughests and best possible AP or Wi-fi bridge, that's also compatible with DD-WRT software? Possibly with N support as well?

Ussually, I just went with the WRT54GL and flashed it with DD-WRT and it was good for a wide range of casual and professional clients. But now I'm suspecting I'm slowly declining into a chasm of old and outdated hardware. Any suggestions?
