Oh, let me tell you about my ski boots... While they don't leak, they are killing me!!! A leaky mask (got one of those too) is a very minor nuisance in comparison - I don't even notice anymore... but agreed, a well fitting mask is nice...Yeah, @stuartv has it right.
You just never know until...
We can complain about cost and value, but once you find the mask that fits YOUR face, everything gets so much better.
And if it cost $30 or (gulp) $230, it doesn't matter. You're a happy (albeit poorer) diver! Hey, at least we aren't skiers!
