It is a long history, including a few hand-made boards and sets, but in
Internet you can find good offers for, at least, good conventional Chess
sets, and for rarities, as you did. If you want to play some variants, I
am afraid that the best you can do is make yourself the set and board, or
looking for an artisan to do that, but some commercial sets can help, like
Omega Chess sets, by example. With ceramic tiles you can construct almost
any class of boards if you want, also, but unconventional pieces is a bit
more difficult, and some work is needed.
