as for the aqualifter failing one day, if you keep both ends of the tube underwater and check on the pump once in a while, even if the pump fails, having both pipes submerged will prevent a break in siphon.
And both box overflow and drilled overflow are used to feed a sump so not quite sure what you mean when you say an overflow box is more likely to screw up than a sump. Yes, a bulkhead is cheaper but sometimes that just isn't an option for people.

Haha, im not quite sure what I meant either? Im pretty sure that was supposed to say that a chance of overflow is higher with a hang on overflow than with a drilled tank.
I've heard of many cases of syphon pumps failing. Im just saying that going drilled is a better safety guarantee and unless a tank breaks there is essentially no risk of overflow if set-up right.
