Formulas are probably the best value in biking. They're basically every bit as good as a Phil Wood or Dura Ace (especially considering how the average rider will use them), for a small fraction of the price. The Formula/Deep V combo is a pretty popular one that should yield you a good solid wheel.

If you plan on building these wheels to learn wheel building, you're on the right track, but if you think you're saving money, I recommend you reconsider and buy a pre-made wheel. They're often 25% or so less than the cost of making one yourself.
