Check out OSTC if you get a chance. They are German company and I know few posters here cannot say enough good things about them.
The OSTC is a thing of beauty, quite a few of my friends have the OSTC 2 and are very happy with it. Indeed the OSTC 4 is on my radar for a backup DC
But none of the the range as yet run AI
Fully understand @Neilwood reasoning behind an LED screen, I'm a big fan.
On all the DC he listed you have alter the conservatism so you can get close to your buddies NDL
On the Eon you can set a number of different profiles. Pre sets if you like, which remember your screen layout and other settings. I have one specifically for guiding which I switch to. This has my conservatism taken down so that it matches the shop computers. So I know what their NDL times are
For fun dive I go to my normal setting. Again to the OP well done for suggesting that you might be better off using a more conservative setting, rather than seems to be the fashion of wanting the least conservative setting.
