Looking at small 15 gallon boomless sprayers to mount on a 400cc quad. Fimco, Plot Pro, North Star, Tractor supply and Rural King seem to be the most common. Want to keep price under $300. We have small 1/4 -1/2 acre plots. Some areas will be in the woods so I don't think I need a large capacity . Water is easy to access. Reading the reviews seem to run the gamut from great to crud. Any brand to stay away from? What about pump GPM size. Any other info would be appreciated.
