Check out the
HZ-300. It is under a grand and is strictly a hazer. The only issue is it is oil based.
If oil based is an issue, check out the
X-310. It costs more, but is water based and can work as a fogger as well. If too much money, check out the
Z-300. It is a lot cheaper then the X-310, but has about 40% less output and no DMX control either.
If using the X-310 or the Z-300 for haze, I would recommend
X-Fog Pro fluid since it hangs loner then X-Fog fluid. Oil based will give the best effect and hang the longest, but some places won't let you use it, some people hate the smell, and it will leave more of a residue behind then water based will.
