You guessed it...fist time homeowner

We are updating our kitchen with new countertops, which led to new sink, new faucet and insinkerator.

Plumber visited us today, and gave an estimate of $1,500.

This sounded outrageously high considersing we have already bought faucet, insinkerator, etc.

Is this the ballpark for price range or should we just keep looking?
