Halloween // Cheap haze machine recommendations?

I've been looking at fog machines to use at some parties I hold with ~15 people but I've been reading that haze machines are better because it makes the lights pop more, without clouding up the whole room and the haze wont dissipate as fast as the fog does, I've also read something about incense? but i'm not too sure how good of an effect that will produce. Just having trouble finding haze machines as mostly everything is fog machines. Just wondering if anyone has recommendations for $50 - $100 haze machines? Not too interested in renting a haze machine as-well. Thanks in advance!
