Leviton Hospital Grade AC Outlet - Which One?


I've decided to go ahead and buy a Powervar ABC1200-11 power conditioner. It's my understanding that even though these units were made for medical usage, they have two versions of this model - one with regular receptacles, and one with hospital grade receptacles indicated by a small green led on each receptacle).

I'm thinking about going to DIY route and upgrading the AC receptacles to medical grade ones (and possible putting in an IEC adapter to roll my own power cable). Ebay seems to be the cheapest place to get the AC receptacles, but there are two different hospital grade Leviton outlets that suit the bill. I'm hoping to get folks' opinions as to which one I should go with.

1. self-grounded outlet

2. isolated ground outlet

The only difference is that the more expensive one has an "Isolated ground devices have a grounding terminal that is electronically isolated from the strap to eliminate electrical interference (noise) in grounding networks that can cause problems in modern electronics", while the cheaper one is "self-grounded".

What are people's thoughts on this? Thanks!

One more voice says avoid the Leviton, the P&S and Hubble outlets sound much better.
It certainly looks like the consensus is clear - stay clear of the Levitons! This helps out a lot. Thanks for the opinions, folks!
Hubbell HBL 8200H and HBL8300H non plated.
(See page 10)

8200H 15 amp
8300H 20 amp

Guts are the same, 20 amp rated. Only the faceplate is different.

A good "rule of thumb" is that not all Hospital-grade outlets are necessarily audio grade. The Hubble 8300H/I is definitely audio-grade. You won't find these in your Home Depots or Lowe's. Albert Porter has these as his Porter Ports. Only difference is he has them cryo'd. Replacing the stainless steel neutral screws with brass puts the final touch to them.
