Screen trap pan covers

Where do you guys get a good stiff wire screen for pan covers for the pipe dream set.

The best there is come's from Craig O'Gorman. I am sure there are other people and places out there. Post this on the Trapper Talk or Just Trapping and you will get more answers. Hope this helps.

Craig's is steel screen, which can rust after time.
Aluminum screen is available at most hardware stores.
