What size tires?
If you're really pinching pennies almost any 36 spoke front wheel will work as long as a wheel builder has gone over it. Spend the money on the rear wheel since it's the one that takes the biggest hits. As nice as butted spokes are they aren't as important as the build. Quality Products/Handspun makes good wheels.
Bikeman Quality Wheels Pavement Rim Brake Rear Wheel 700c 36h Shimano LX / Mavic A319 / DT Champion All Silv price seems to have crept up on this model but it's a fine choice.
Again if you're pinching pennies spend the money on the rear wheel.
