(This isn't exactly what you're looking for as this one has a standlight in the rear but not the front, and the front light is better mounted on the fork crown rather than the handlebars, I prefer this as it means it's permanently attached so no faffing each time you stop/start and much less like to be stolen.)
I already had the lights so I paid £45 (inc P&P) for just a wheel (from the eBay shop of the same seller, they have black rims there).
I'm planning on building a new commuting wheelset so really was just looking at using a dynamo hub for the front so it all matches. Possibly even buying a 3rd rim.
For a very cheap and cheerful one, about £40 for the wheel/hub/lights and £15 for postage from Germany.
