I'm guessing you don't have much of a concept as to the obscene amount of time, effort and energy it takes to fabricate a lugged bike frame by hand.

The Quickbeam costs the same (maybe a bit less) than a Cinelli Olympic, which is made from the cheapest 2x butted steel tubeset Columbus offered at that time (Thron). The Quickbeam costs substantially less than the Cinelli Supercorsa Pista, which is made from the least expensive steel tubeset Columbus currently offers (Zona). I have no idea what tubeset the Quickbeam is built from, but I'd be shocked if they used anything lower quality than Thron or Zona. Obviously, the Cinellis and the Quickbeam are apples and oranges, but the point is that quality, handbuilt, lugged bikes are expensive.
