Yes I do, and I think they should be beginner proof and intermediate proof and "master" proof too, if it means having:

1. a system that forces the monitoring interval necessary to catch most types of diver error.

2. a system that forces continuous involvement of the user to maintain it's operation.

3. a system with an outstanding low fatality rate.

4. a system that reinforces safe operation, building on the safe habits taught in training.

5. a system that instills vigilance throughout the set up and dive.

6. a system that penalizes you every time, in mostly forgiving ways, for lapses in attention.

7. a system that discourages a level of task loading which distracts from the adequate monitoring/maintaining of the system.

Why reinvent the wheel, this seems remarkably easy to achieve. Add all the monitoring bells and whistles you want, just leave out the set point controller.

Yes, I'm all for it!

(I do realize my current preferences are not backed by conclusive research, but at the moment it seems that the market trends are being driven by market pressures and not science, so i'm not waiting around for facts that seem likely to never come.)
