When we took the ship tour to stingray city, the equipment they had on the boat that took us was VERY CHEAP!! I found a mask and snorkle at HEB in Texas for only $16.99 and have tested it in the swimming pool with GREAT results! It doesn't leak at all and is very comfortable. I know you "get what you pay for" but remember the tours use cheap stuff too because they are used and abused by tourists. I was lucky to find this deal and glad I'll be taking my own this time!!
