Funny enough, they seemed pretty common on eBay when I was searching for coal cars a few months ago. Of course, now that someone here needs them, they've become as easy to find as Bigfoot's toenail clippings. Ripley, I'll let you know if I spot any.
FWIW, I ended up using the empty "Sodor Mining" hoppers for coal drags on my railroad.
