Snorkeling vests available on the PG?

Does anyone have any up to date info as to whether the PG has snorkeling vests available? I usually snorkel without one but on a recent trip to Curacao I was given one with the equipment we hired there and it gave me more confidence swimming in deeper water. I've heard different opinions on whether they are available, if anyone has any info that would be great thanks. :)

When we went last year I brought my own. I got it off Amazon. I love wearing it because I feel a lot safer and really can enjoy myself more.

I was there a year ago and there were no vests available.

Thank you Cruisefun27 and Ducklite for your replies. Looks like I will also be ordering a one from Amazon!;)
