FWIW- I don’t have any experience with those machines, but I’ve got an Earlex 6003 that I’ve been using for several years. It’s above you’re price range, but it’s an awesome unit. It sprays anything I’ve asked it to, is easy to clean, and is a quality product. It’s a step down from the higher end stuff, but is defiantly not low end.
