A local dive shop explained that high quality masks are made from tempered glass and silicone. The cheap ones are all plastic. The masks at the dive shop were $50.00 and up.
At Decathlon, I found a number a reasonably priced plastic sets for about $20.00.
I decided to go with a tempered glass and silicone set that I found at Sports Athority for $39.00. I tested the mask at the indoor and the silicone seals really well and is comportable because the strap does not need to be so tight.
