They are still available used ( ebay etc) and are well worth the effort to find in my opinion. The knockoff claw anchor works ok but not nearly as well made as the original. I'm sure the Manson/Rocna types may be even better anchors but don't work well on my bow-sprit. The most common combo I saw in the Bahamas this past winter was the Bruce/Delta. We used the Delta a lot as well, and like Dave stated the wind was strong and continuous.
