I've bought a pile of stuff this year... basically full kit for two people. Purchases were made based on readings here, advice from friends/instructors and perceived value.
Other than BCD, our kits are essentially identical, so two each of:
Henderson 5mm thermoprene jackets.
Henderson 5mm booties - wish I'd gotten some with zippers.
XS Scuba power fins with spring straps.
ScubaPro LadyHawk with Air2 (hers).
SeaQuest Balance (mine).
Air2 added to SeaQuest.
scuba.com titanium knife (bolted to her BCD).
Wenoka Squeezelock (came on my BCD).
ScubaPro MK11/G250V.
Octo-length hoses for the second stages, since we'd be donating the primary.
Aeris XR-1NX with compass.
SMB and spool.
Various bags, clips, retractors....
Still to buy:
3mm fullsuit (for me) and 5mm full (for Sue).
Lights and backups.
Booties with zippers.
ScubaPro LadyHawk weight pouch (one of hers is on the bottom by the Aquarium off Playa del Carmen, if anybody finds it...)
ScubaPro tank strap (I prefer theirs to the one on my SeaQuest, so I'm changing it.)
Foldspear (Lionfish are kill on sight, but only if you have something other than a dive tool...)
