Hi George,
I didn't think about plastic version but good news, if you ever decide applying this mod there are plastic sifters with smilar design which works exactly same as stainless ones. I'm not sure where you can find them though, but I saw a couple at google images.
Also there are sifters working with batteries ( here you can see an example )
alternative mod --> you'll grind into this vibrating one, then let it vibrate through a funnel into your portafilter.
