Depending on what type of diving your going to do, the OMS or Oxycheq are great. I own a rear bladder OMS and a Oxycheq Recon for side mounts or regular rear mount. I use my OMS for all my diving at the moment, it is really versital. My setup includes double LP 95s with two Genesis regulators with DIN conversions, small Pelican lights and a Sartek cannister light, problem with this is that the steel LP 95s are heavy as hell, I also have a set of double 80s which are much lighter and make for a more enjoyable day. I would make a tank suggestion with HP 100 or single LP 95, as for diving wear I use wet and dry depending on my mood.
