440's/440i's are fantastic affordable little machines that will pay for themselves 100x over. I love them for what they're meant for...which is to run 50(preferred)-100(tops) feet of 3/8 with a 517 tip. They'll do it all day, every day for years with really good maintenance and an occasional repack. They aren't made for heavy viscosity coatings, big tips, or long hose, or spraying too far vertical. Use them for what they can handle and they're the best deal on the market. Abuse them, and it's not the pumps fault when it fails you. If we're spraying elastomeric it's coming through a 1595 or a GH230.
