http://cgi.ebay.com/Backpack-Gas-Power-Sprayer-/280465165157?pt=LH_DefaultDomain_0&hash=item414d06cb65I found this on craigslist for 125 bucks, looks and runs great. I know it is not the best made brand out there [China made] but it sprays great. The problem is that it has a shrub and tree type gun and has a lot of pressure even with the regulator turned all the way down. I would like to use it for herbicides on turf. So, does anyone have any suggestions? I was thinking of a chemlawn gun instead of a wand, but I think I would empty the 6.6 gallons out too fast.
