Constant Kitchen Sink Repairs

I am so discouraged and have spent so much money on plumbers and my Price-Pfister kitchen faucet (15 yrs old). Constant leaks; one fixture after another. Parts replaced, then another leak. I have no mechanical skills whatsoever and would need a plumber (again). Shall I quit throwing good money after bad and just replace the fixtures? And say what to the plumber, so they don't know how naive I am.

Maybe you need better repairmen. I repair PP faucets all the time and usuallyreturn to the house years later to do it again. They are either not using good parts or are doing it wrong if you have continual problems with the same faucets.
