Assembling your own bike can get you more bike per $ in certain cases if you shop around, will accept some used parts and some NOS parts. In my case, I bought a slightly used frame, components a couple years old, but new, some generic 50 mm carbon tubular rims, and built my own wheels. I think it's "better" than an equivalent new bike for $1300. It has the drivetrain & wheels that I want. But it's not "new", does not have the most up-to-date parts, or have a warranty.
