Call (don't bother with email) Mike Garcia at oddsandendos.com. He will be able to build you a light (1500-1600 grams) strong superbly built pair of road fg wheels easily within your budget. I suggest lacing Niobium 30 rims (the same as IRD cadence), to formula hubs with some oval or strongly butted spokes. He will also send you the parts to build yourself if you want to go that route.

Hint: since you are building road wheels, use a light front road hub, like the Specific perception hub (for example)...you can easily save more than 150 grams without significantly adding to the cost.
