recommendation for a good NBN router

I'll be getting my NBN connected in a few weeks and it seems like a good time to retire my old WRT54G routers. Does anyone have a suggestion for a router that is: cheap reliable 802.11n dual band easy to put OpenWRT on Also, does anyone have any good advice about getting OpenWRT working with the NBN? Maybe it's trivial - I don't know... thanks, Cory
