I've been very pleased with my Velocity rims (aerohead) and Formula hubs wheelset.

I think you can go cheaper on components if you have a decent wheelbuilder locally. Or you can learn to build wheels yourself. It's not that hard but takes patience.

Factory build wheels will still be cheaper but check them out thoroughly and if in doubt, have your local wheelbuilder check them. Sometimes the spokes are not evenly tensioned or too wound up or there's a slight wobble.
