But are those really worth the price over something like Mako or DGX? I have a Hollis M1 and my wife has the Atomic Frameless, and we both have a DGX as a backup mask. We have said to each other that we really can't tell the difference when we switch to the backup masks.
A buddy gave me a SP mask because he was getting out of the hobby. There is not ~ $100 difference between that and the others. I think he said he paid $130 for it? Crazy.
The S and the P on it must be made of gold!
