I bought a used frame (ebay) and built it up part by part. New framesets are typically so overpriced relative to buying the complete bike that it makes more sense to buy the bike and swap out some parts (selling the unused parts to recoup some of the $$$).
For example, a P5 Six frameset is $7,000, while a complete bike (Dura Ace and HED carbon wheels) is $8,500.
