Ok, I'll try to help...
Oil based hazer = ~2 micron particle size
glycol based hazer = ~20 micron particle size
You can see from the above that oil baser hazers have the potential for a much longer hang time. Good (notice I said 'good') oil based hazers are pretty expensive though. Think MDG Atmosphere etc.
I have a Look Solutions Unique 2 hazer which I find to be an excellent compromise, this unit hardly uses any fluid, has a decent hang time and gives a nice even haze. However, I guess this would be overkill for home use.
The key to not getting residue is to use sparingly and not fog the place to death. Also, the more modern units seem to do a much better job than some of the older units. Remember also that in nightclubs the units are being used night after night, in your home you will more than likely only use it ocassionally. I believe BBC TV use MDG's and Pea Soupers, both are oil based hazers. They wouldn't use them if they left a mess as their camera lenses would soon get soiled.
If your just doing shows at home pretty much any cheap hazer or fogger will probably be ok for the times you're going to use it. Hope that helps you
Cheers
