I'm going biodynamic so I'll be doing a lot of spraying and I purchased a Chapin 2-gallon sprayer. After using it once with water, I'm ready to return it but I need a replacement and all the sprayers at my hardware store look pretty cheap.

I'm unhappy with all the pumping needed as well as not being able to adjust the nozzle for more spray. The nozzle also looks flimsy.

I probably need a backpack sprayer with at least 3 gallon capacity, minimal pumping and a nozzle that can deliver a fine mist to large drops. Can anyone recommend a good one?
