Which one AD7000 or NA-D7000 or Nexus and WHY???

I would like to hear from someone that has the Nexus D7000 housing as well. I love my Nexus D90 housing and considering the upgrade.

My Nexus D300 works great. Very compact & ergonomically friendly. I especially like the threaded ports. Very secure & don't have to worry about locking systems like needed on bayonet mounts. Since I have both Nikonos & F/O bulkheads I can use either. However since buying the D300 I've only used F/O with a pair of S&S YS27's. This has been a very reliable system, and I like how compact it is (especially when diving in current). Buoyancy is slightly negative, which I prefer. I'd expect the D7000 housing to be similar, but haven't tried one yet.
