Query: too disposable

Hmmmm, what can I say. It works okay when its new but there are just too many problem components. Things wear out too fast and need regular replacement. The money you save on the original purchase price is sucked out of your pocket on upkeep. Opening the container to add paint is a nightmare. The composite plunger portion of the pump breaks way too easily and you have to buy the whole cartridge to get a new one. I broke the ceramic tip once and, same thing, had to buy the whole replacement cartridge to get a new one. Hey Wagner, I wouldn't mind paying an extra $50-$75 for a better product. How about that?
