What is the most economical way to get a water meth setup? Can I build one on the cheap? what company sells it for the least? Any input is great!

 

devils own is the cheapest. works good. the controller is way small.

 

Just buy a 220 psi pump, and find a bottle of windshield fluid. One or two hoses tee together. Some kinda of nozzle. On/off switch. That all you need. Fill in the left out parts but that's pretty close, to a cheap system. Have fun.
