Which is the best craft puzzle available online?

[AllenHed]

Hi all, I have been searching for some quality wooden jigsaws lately. A friend recommended a few classic puzzles by small workshops. I'm wondering where to get rare wooden puzzles these days.
 
Furthermore, does anyone know where to find these wooden sets or which designs collectors prefer? I really liked the smooth laser cuts finish. If you know where to get these custom sets, I would appreciate the advice!
