You are not out of line -- in fact, you're acting very prudently.
Question for consideration:
Would you rather have...
a) The dealer do it begrudgingly by a mechanic who'd rather be doing something else, or...
b) Your local trusted-mechanic do it since he wants your continued business
You're obviously going to "pay" for it one way or another.
