Quality outlets for non-audio

Second the Leviton commercial grade. Also, when replacing outlets rewire them to the outlet screws if the old ones are connected to the push in connectors in the back. Those connections have considerable resistance and can cause power quality issues.

Hospital grade are not to expense get them be a sport.

I agree with @ebm, Leviton makes hospital grade outlets, and they weren't expensive. 
It is what I use now.

I second the Hubbell recommendation, put a few in my folks place. Leviton has been find for me so far, but the ones I replaced were Leviton. Just installed some Acme Audio outlets for audio, TV and computer rooms. Now those suckers are TIGHT.

+1 to @jea48 comments. In particular, what is important is that the outlets be spec grade (usually so labeled) rather than contractor grade (often unlabeled). Contractor grade are the ones you can buy at Home Depot for 35c each. They don't last. The brand of outlet is secondary to the importance of buying spec-grade ones.

I find TR outlets a pain in the a$$, but I suppose they keep small kids and stupid people safer. Once you get the hang of them, they're not so bad.
