Decent price for Timing Belt on NG?

[David]

Car is my 87.5 CGT. It's time for the timing belt. The local wrench said $150 labor (3 hours at my discounted rate of $50 per hour), plus $20 for the belt. Water pump (if it is run off the belt, I will replace at same time, if not, it will wait) not included. So we're looking at $170 + tax out the door. Does this sound like a decent price? Also, are there any other parts that ned to be done at the same time as the timing belt? he didn't indicate any other parts...

TIA,
