Aeris is the sister company to Oceanic. The AT 400 Pro is the Aeris version of the CDX5 first stage and a Delta 3 second stage. I have two CDX5's and both have done well for me over the past four or so years. Both were recently refitted with new HP seats due to the recall that both companies issued. One reg still had a problem and when my LDS tech called Oceanic about it the response was 'send it to us'. It's back, and so far is running fine. I personally have not used either an AT400 or Delta 3 second stage, but many buddies of mine use the Delta 3 and very much like it. I do not know anyone who uses the AT 400 version so I cannot comment on it. The Gyro octo is Aeris' version of the Oceanic swivel octo. I own three of the Swivel. Very small, lies flat and does not have an 'up' or 'down' position when donating in an OOA situation, it works in any orientation. These octos, due to some mechanics in the design, do seem to be a bit more finicky and require a bit more tuning than a standard design octo.
At one point I had an Aeris computer but did not like it. It was not as adjustable (in terms of setting limits, alarms etc) as I would have liked. Also, the battery seemed to die very quickly, and usually with about 10 seconds of warning. I still own that computer, but now it's only around as a back up to a back up.
Many of the postings have advised you to shop around before you plunk down that kind of money. I agree. There is a ton of good equipment out there from many good manufacturers. For BC's there is Sherwood, Oceanic, Seaquest among many others within the jacket style. There are also back-inflate types like the Scubapro Knighthawk as well as the more modular BC's like the Dive Rite Trans Pac, OMS IQ pac and the true backplate/wing styles from Dive Rite, OMS, Halcyon and Deep Sea Supply.
Some of what has been mentioned is great advice. Shop around, compare, try as many different brands/styles etc as you can before you decide. Talk about what kind of diving you want to do with folks at different LDS if possible. Ultimately you will be the one diving this gear, so you should be comfortable with your choices. And with the cost of gear,it will probably be with you for a while!!
Good luck with finding the right set of gear!
