Plastic fill plugs?!

I need a new thermostat fill plug. Getting tired of the black iron pipe plug with which the DPO has graced me, and the accompanying fine mist of antifreeze under the hood. The Usual Sources list a <span style="font-style: italic">plastic </span>plug as a replacement. Anyone have any experience with these? I'm no engineer, but plastic threads against metal and really hot liquid sounds, well, odd to me.

Anyone still carry the <span style="font-style: italic">brass </span>plugs for something less than an arm and a leg?
