I took a chance and bought an Aircat 1/2" impact today. They are supposed to be less noisy than most air tools and are made in the U.S. This particular one says 640 lbs. max torque.
It's coming in the mail so I'll let y'all know how it is. If it's quiet like they say, I may go for a ratchet as well.
