I do think you're less likely to have trouble with low-price scopes on low recoil, especially short range, weapon.
Short range diminishes parallax problems, light gathering issues, magnification changes and low recoil helps cheap parts stay together.
I think Art is probably right about the internal adjustments being the most likely weak link. I've personally never had trouble with magnification or parallax adjustments but the one scope that did fail was suddenly 6 feet left at 50 yards and no amount of turning the knob moved it one iota.
I've never been a "knob cranker" though, using hold-over instead, so I can't say how most of my scopes would have held up to repeated adjustments.
Still though, many a cheap scope has served well on 12ga slug guns and long range varmint guns.
The short story is that a guy who can't afford to drop $750 or even $250 on a scope (and I've been that guy ALOT) should not feel cheated or like he can't get decent, trustworthy optics.
