I decided against the QTX because of its low output and went with the American DJ Fogstorm 1200. The price was suspiciously low but so far I haven't discovered any bad points. The remote control however was sold separately for a price that was suspiciously high so that equals up :P
It's a fog machine instead of a hazer but I can live with that. It even has no warm-up time in between once it is heated up so I can have continuous fog output if I wanted to. It was able to fill the living room pretty quickly to a "can't see a hand before my eyes" amount of fog and it lasts quite a while.
The biggest downsides are the noise it makes and a rather high fluid usage, but maybe I'm too much biased by my late very economical Antari F-80z.
