I haven't tried the commercial ones, but have mocked up my own from various readily available materials. YOu can use the archives here on Tweaks to find a plethora of ideas and opininons.

FWIW, 3 items to consider in outlet covers, whether you buy them outright or make them:
1) non-magnetic materials - stay away from steel or ferrous stuff
2) vibration controls
3) RFI controls

You can successfully use: ceramics, metals that are not ferrous, wood, plastic, nylon, etc. They'll all work differently.

For vibration controls, heavier and duller materials work best IMHO. That means that if you tap the materials and they ring, it's not the best, but if they thunk, you're better off. The commercial biggies (Oyaide) use duralimin, a very vibe absorbent aluminum alloy that is thick. I've tried non-ferrous metals of the thin variety, and they do some grounding if set up right and maybe some shielding, but they are not good for controlling vibrations. Wood, ceramic, nylon work better. In fact, the best to test it I've found can be those non-ferrous heavy cast metal outdoor outlet covers. They have weight and will do whatever grounding/shielding closing the metal box gives you (assuming your box in the wall is metal - if not, then you get nothing there.)

For RFI control, nothing I've found beats carbon fiber. I might try the Furu with CF over brass, but I think it's too thin to be tremendously effective. I'm using CF aircraft blanks (thick)over the top of the outlet cover and a couple of CF layers glued onto the back of the cover too. Those work very well.

Lots to play with.
