i think that if you're looking for something that's gonna withstand hard city riding, you should be looking for a good builder rather than just specific rims and hubs. a good wheelbuild by someody with experience is going to hold up more than all the deep v's in san francisco put together^2. it might cost you a few bucks more, but it's worth it to find a shop you like and support them instead of just buying some hastily built wheel from greatbicyclewheelsdotcomslashindexdothtm or where ever.

stroll into some bike shops around you and see what they have and what they can get, and what they recommend. formula and surly hubs are good, midlevel, generally affordable hubs. mavic and velocity make lots of solid rims. i like velocity aeroheads, because the deep v is a bit much, kind of unnecessary, and overly stylish for me.
