I know what i have used for years.
Seaquest... now Aqualung pretty good jackets and back inflation built strong, but heavy
I used the fathom one from oceanic in singapore and can't say anything but good things about a simple idiot proof single tank wing and aluminium backplate. I had one of the first gen and the finish wasn't great on the plate, but hey black on black with some wear marks just makes u look more garang
I now use halcyon custom traveller pro, expensive and a tad finicky...sticky inflator and dodgy bladder cover ports, sorted out by factory, but at the price should have been good to go.
my GF uses scubapro the litehawk, a super no frills back inflate bcd.
and now an old second hand god know from where transpac II with old traveller wing (she loves it btw).
they are all good.... just remember one particular thing.... FIT is the most important.
It has to FIT your body and your style of diving.
no point getting a huge bladder and diving singles for example
happy shopping and safe diving.
