yup i've got a 700 watt fog machine that works great for filling small to medium sized rooms full of dense fog, cost $40 at a local party store (didn't wanna wait until haloween ) besides mine even comes with a timer i can set to maintain a level of fog
I have a 1.7kW fogger, works great at home and events. Sucks up power though, but its great! A hazer would deffinately be better, but the cheapest one out is like $300
