A guy at our club has a cheap Stevens. He has had it for several years and probably put a thousand rounds through it. It recently broke. A Beretta or Fausti would not have fatigued that quickly and would probably not have broken, yet. Factor in the additional repairs and shorter life of the firearm, and the cheap guns are usually the most expensive.
More importantly, the fit of the gun to the shooter should take priority in the selection. It costs more to make an ill fitting gun fit properly than to repair a cheap gun after 1000 rounds.
