I just bought two cambio rino bikes... any way of telling if they are "better quality" ones?? they are both Columbus Zeta Tubing and have engravings in the frame. Both have RINO engraved in the rear seat stays by the seat post, on one of them the top of the forks are flat and slanted down with "Cambio Rino" engraved and the other has rounded smooth fork tops with the same engraving... both take current allen key bolt brakes

I only bought them because I collect bikes with engraved frames because of how unique they are (and I got a good deal) but I'm just curious if they are the better ones. One was $200 and the other one was $300 (the $300 one had been switched over to all campy victory components)

thanks!
