At the low end, you could stay with a Tiagra hub/Mavic Open Sport setup, with a clyde worthy 36 spokes, for low dollars, like:
This wheel at AEBike.
I'm having great success with a Velocity Dyad, would highly recommend it! My OpenSport kept breaking spokes, though with 36 spokes you might be okay.
note: i'm considerably heavier than you, though I don't pack much gear
