This really is the largest high-quality 20X loupe. Though even with this high-quality triplet, they are at the limit of what can be done technically - although the image is crystal sharp in the centre, it is just a bit wobbly around the edges.

Incidentally, I did once sell a genuine large 20X for half this price, but the quality was so awful I got fed up with people returning them and I discontinued them.
