I also agree with you on the mask. I've tried on and/or purchased probably over 20 different masks and I always get a leak (odd shaped face I guess LOL). I've finally found a mask that doesnt leak. I know am ordering two more for the eventuality of the mask getting discontinued! Once you find the right mask, cherish it, and back it up. For some of us it's harder than finding the right fit withjeans LOL!
on the bang for my buck list is either of my dive computers. my Cochrane or my Shearwater. Ive got to have one of them. I can borrow about any piece of gear but either of my computers are must have.
The other item is my mask with the lenses bonded into it. I have to be able to see to dive!
