How about a set of Formula high flange, flip/flop hubs (32h fr/rr) laced to Velocity A23 rims? I converted them to tubeless using Stans rimstrips and have been using them on my road fixie. Never ridden off-road, perfect shape. They're "track" hubs, but have hollow axles so you can run QR skewers. I've got chain tensioners to go w/ the rear. $300 plus a little bit for shipping (US shipping only)
Not mine, but a pretty sweet wheelset for the price. You may need to register to see the pics.
