I have normally been paying between $65 - $90 bucks for my IST mask. I am hard to fit and this one does the job for me very well. One of the posters, and I am sorry, I can't remember who turned me on to a site where I could get the mask for $30 with free shipping AND IT INCLUDES A NICE MASK STORAGE BOX. It's shiny (black) and new and smells oh so nice. I can't go diving but I can "defog' my mask. I have already run the cigarette lighter under it and now doing the tooth paste thing. I can't wait for my hole punch to arrive so I can install a purge valve in my (also new) DataMask. My only regret, I should have bought 3.
