I got an aluminum frame from chucks as well for my wifes bike. The frame was only $55, it was straight gauge tubing, and fillet welded. It is indestructible (for aluminum). The reason he says it's not for an avid rider, is because it is heavier, and very stiff and unforgiving. Most avid riders are looking for lighter weight frames that will have smoother riding characteristics compared to cheaper frames. Frames like that are easily worthy of a 9s 105, or Mirage group, maybe even Veloce.
