The labor is less for a replacement, than it is to repair. I acknowledge that it is much cheaper to repair. Now might be a good time to consider whether features will drive your decision.
On my Maxum the galley faucet had a separate hot and cold knob on the mixing valve. The faucet was mounted sideways, so the hot knob while technically left forced you to reach around essentially 'behind' the faucet to turn of the hot side. Plus, to turn off the water, you had to turn off both knobs. This forced you to take time to readjust the flow to get the write temp each time. I wash dishes like a military shower, so this was really cumbersome to me. I would have preferred a single lever mixing valve that I could mount on the right side of the faucet, making it inboard rather than outboard. (Maybe yours isn't like that).
Maybe a spray option, or a removable head to use like a handheld sprayer. I just replaced my galley faucet with exactly what I'm describing. Just a thought.
