I've needed to replace the kitchen faucet in the house for a while now. It's not repairable, it's just worn from 20 years of daily use. I'm looking at things, seems like all of them leak or quit or are just crap. Those built-in spray head units are popular right now, I haven't found a one of those that doesn't have reviews like "pretty much lasts a year." The handles on the selector break off. The spray heads quit. They're partially plastic and the finish just comes off. The old two handle units? Leaks, cheap ass metals corroding away quickly, even ones where the cartridges just snap and you can turn the handle 360°. Most put cheap-ass plastic lines directly on the units, so if you get a bad crimp or a hose that's bad, you throw it away. The only ones I've found so far that won't break the bank are mid-grade commercial units. They're not pretty, but they're made from brass just like the old ones. That's probably going to be the one.
