You can purchase gear at Utila Dive Center, drop them a line and find out what they have to offer and the prices... Roatan has a dive shop in the West End that sells Mares, the Bay Islands are now duty free so the prices should be reasonable...
I had 2 divemaster trainees purchased Mares masks this past summer and they fell apart after being used just a few times (skirt detached from frame), the design of the mask frame was poor, The exact model doesn't come to mind, however, the model is irrelevant as nothing should fall apart quickly, poor quality assurance?
I had a Mares BCD 2 years ago, Mares Vetor Origin, this thing fell apart after after 100 dives (seems leaked and the inflator had to be replaced), also, I have a colleague who purchased a Mares Dragon about 1 year ago, something in the weight pocket locking mechanism failed and we could not get the pocket out of the BCD or get around the plastic covering which is too complicated;If you purchase a BCD with intergated weight pocket, make sure the locking mechanism is very simple.
I suspect with anything manufactured, apply the KISS theory, Keep It, Simple Stupid. Mares does have a good name, but my experience has shown me otherwise.
