ULV Fogger Q

Anyone have any experience using an Ultra Low Volume Fogger to dispense pesticides?

I remember Hadley Cash talking about the electrostatic fogger he uses and how effective it is.
The material is charged as it passes through the nozzle, the particles are attracted to all surfaces and wrap around all sides of the plants and benches and gets into all crevices. Apparently very effective but...
After checking the prices, the Dramm is several thousand dollars.

So I thought I would look into the next best thing, the ULV foggers.
While not as effective, the cost is "only" a few hundred dollars... it breaks up the material into micron size particles.

Thoughts on using them?
Pros and cons?

Thanks,
Jim T
