Not sure why they're "hard to find" but there are several on ebay right now. I had one...sold it on the Stitchers Guild forum along with several other cams/accessories a while back. If there's an OSMG close by, you might try there. Mine retired a while back but when the shop was still open, he had huge boxes of Singer cams that he was selling for $1 each. That's probably where I got mine....
