Harris Cyclery has a deal going on right now; a rear wheel built around a Nexus 8 for about $260 or $270. Seems like a good deal, a built wheel for about what the parts would cost.
Even if you just want the hub, they're probably a good place to get it. For one thing they actually have experience with them, which you're unlikely to find in an LBS.
I was about to go that way when I realized that I have vertical dropouts. Time to go garage sale-ing in the spring I guess.
