That is a difficult question for me because most companies that make puzzles, make fantasy and science fiction puzzles, some times they use similar pictures. I do not know of any particular website that specializes in Sci-fy and fantasy puzzles. Maybe Buffalo puzzles for a reasonably priced, mediocre puzzle would be a good place to start. They have puzzles made in USA and China, both are similar quality but a little different. We live in USA and often find good deals on Amazon. Buffalo also owns Ceaco and the Ceaco Silver Selection is the same as the Buffalo Silver Selection, only difference is the name. There are higher quality puzzles that cost more , for example Ravensburger is a higher quality, but cost more. Let us know what you find and please consider sharing pictures of your completed puzzles.

Some board game shops could have some.
