Here's what I am having built up, you could go with a 32h setup if you want the strength, but I'd discuss with a knowledgeable wheel builder about how much is too much.

White Industries hubs: H2/H3, Campagnolo 11sp, polished silver
HED Belgium C2 rims (23mm wide, 25mm tall), 24/28h
CX-Ray spokes front and rear non-driveside, DT-Comp drive side.

That build was quoted to be around 1500g, should be plenty strong as a daily riding set for my current less than ideal weight, and came in well under $700 delivered. Up the spoke count to 28/32, go with heavier spokes if you want to make something really durable if that's your goal.
