I just ordered the Devious Veron 2 mask.
The mask will run you about 200 but it is the best I have seen.

This link is the veron I just ordered.
Sam is not the creator of the original mask.
He created the the first INDY Myers mask in 81.
He hasn't made a mask to every sequal. He's made a few H1s and H2s, an H4 mask which was made with the screen used as reference in front of him, and a line of RZ1/2 masks from every scene . He hasn't been making Myers for 20 years. His comeback was in 2008 with the HSS Shape 08.
Sam's a great guy who makes great masks
