The wheels won't cost very much more than the cost of the hubs, rims and spokes - so if you research those, you get the answer.
A few years ago, I would have suggested Chorus or Chorus-like Centaur hubs, but these are now discontinued, and I can't even find new old stock at the moment (except for fronts only).
If you can afford it, there's a pair of super-quality Record 36h hubs @ £200 from Total Cycling, or 32h @ £160 from Parker International. At the other end of the scale, there's Ambrosio @ £70 (pair) from JE James.
Open Pro rims are £64 pounds a pair, or £44 for Open Sport, or £32 for Chrina.
Spokes will be about 25p to 85p each. Recommended: Sapim Race or DT Competition.
