I have found that to get something that "lasts" and still looks decent your in the $125 -$150 starting range....whether you want to spend the 600 to 700 for the high end designer ones is up to you....
I am a firm believer that you get what you pay for. Kitchen faucets can vary more than what meets the eye, and sadly some of the features are not known until its installed. Some features, of course dependent on style -
Pull out sprays - quality of the hose, metal or plastic? How does the hose retract? is it weighted ? Magnetic catch to "seat" properly?
Inner workings... the cartridge inside is the engine of a faucet. What is it made out of? Most faucets under $300 are all plastic (generally speaking from my own experiences)... .. if this is your budget, be sure to understand what the warranty covers. Higher end faucets are ceramic and offer more durability plus it gives a really smooth operation of mixing the waters and turning it on and off
Finish - Most faucet lines these days offer a lifetime on finish, with that being said, the finishes do still affect price. Chrome is your most economical, then oil rubbed bronze along with satin nickel tend to be close .. then upwards to the specialty finishes like Aged pewter, Polished Nickel etc. Price difference from one to the next can vary quite a bit depending on the manufacturer.
Last note. If you pick a faucet at a plumbing showroom and find it cheaper online or at a Home Center (more often than not) it is not the same exact faucet! Manufacturers often dummy down models for outlets that are price driven. While they may look identical, if the model number is not EXACT, then you can trust you are not comparing apples to apples.
Becky Sue, I'm happy to see someone else commenting on the quality of certain products at the Big Box stores. I have known of this practice for many years but some clients refuse to believe it.
