This MTM Hydro SG-28 high pressure spray gun (rated to 4,060PSI) is a much less expensive but still very valid solution for those that may not care about having a swivel. This is a little lighter than the Mosmatic solution and looks and feels very similar. I don't know this for a fact, but I'm pretty sure they are all made by the same company.
You have these buying options:
*Wand, Nozzle, and other QDs sold separately.
