Recommended AC Electrical outlets (USA)

What are the recommended interior A/C outlets for 120V/15A?

I note that residential outlets by Eaton or Leviton start at about .60c. I expect these are not even safe in a residential application. Contractor grade are about $3. Probably the minimum I would use in my house. An outdoor "weather resistant" outlet is about $4. Then, "Marine Grade" outlets at WM cost $50. Which there isn't a chance in hell I am going to splurge for.

The outlets I am replacing, some of the terminal screws are thoroughly rusted, and the mounting tabs falling apart. So I would expect those should be brass or something? Is there something recommended that is "marine grade" and significantly better than the residential outdoor, but not as ridiculously priced as the Marinco from WM?

Is the $4 outdoor outlet good enough for a damp location? The worst one I am replacing is in the head/shower, where there was also a portlight that leaked saltwater near it. Though it was installed in a box with a "waterproof" cover so in theory stayed dry.

I use a 20 amp rated outlet. I use ring terminals and corrosion-X, never had a problem in 20 years.
