I am shopping for a new kitchen faucet and considering one of the new (popular?) ones where the actual faucet head pulls out to act as a sprayer. I don't use a sprayer much but like to have the option. I'd rather have fewer holes in my new granite countertop, thus like the idea of combining it with the faucet. What I fear is that the hose may get cruddy and be harder to replace if it's part of the faucet, or the hose won't retract perfectly every time and there would be an ugly gap at the head. Does anyone use these regularly or get feedback on their use? Thank you.
