Guirigay, I've never seen decent snorkeling gear in Negril either. Last year my friend's mask broke, so we tried to find a new one for him ... not even the dive operators had any decent masks. We ended up buying something that was akin to a toy mask. I'd bite the bullet and bring your own ... it's essential gear. Quite often, if I'm not checking a bag, I'll put my mask in my carryon, and then use a karabiner to hook my fins to the outside of my backpack carryon. It's a little unwieldy, but it saves on space on the inside of my bag.
