As said above, VA or Costco. Mine are VA (No questions asked except "What color do you want?) but I have been tested at Costco and was very impressed by the technician's expertise and honesty.
Get rechargeables if you can, and either a small remote or phone controlled. Be sure to mention if you have tinnitus so they can adjust for it.
Edit: I'm the guy who worked in a related business (electronic shooting plugs) and my wife was a teacher of the deaf. So I've had some rudimentary experience in the field.
