What are you spraying level 5, knock down orange peel? You need something like a towable spray rigs to spray massive amounts knock down or are you spraying level 5 in doors with electricity or you doing jobs that have no electric and need gas? Are you doing large commercial jobs that you want a rig on a skid that can be lifted by crane? Anyway here are some new options, I also don't reccomend buying graco hydrologic due to massive repair costs. If you like any just Google the name and add used at the end and see if it's in your price range.
For level 5 drywall finish and skim coats, Graco texture sprayers deliver high performance and consistent high quality finishes. Higher flow rates enable you to work faster and our texture sprayers can accommodate large tip sizes that easily handle a wide range of mud as well as primers and paint.
