I would say get the Niobium 30's from Mike Garcia. I got a set built up with Speedcific Serenity hubs, DT Super Comp spokes (triple butted), aluminum nipples w/ brass nipples on the drive side, and steel skewers for $484 shipped to my door. Including rim tape and skewers, they weigh in at around 1560 grams. The AC's will cost more, and I highly doubt you're going to notice a 4mm difference in rim height. Plus, you can pick and choose how you want your wheels built up with Mike.
