I've got most of them I think. Bullet sense, decap sense, swage sense, primer sense, remote stop.
In order of choice I'd do:
1. Remote stop.
2. Bullet Sense.
3. Swage Sense.
4. Primer Alarm.
5. Decap.
The powder sense would be nice but I don't want to lose a die station for it. The revolution would be awesome if I could afford it.
I tend to watch mine while its running. On 9mm and 38 super the remote stop is made redundant by the bullet sense. When I load 357 sig I get the odd one that falls off after the bullet sense tells the press all is ok. The remote stop stops the press before it moves along.
If you preprocess your brass you won't need to use the swage sense or decapper and the press runs awful smooth. I'm in 2 minds about decapping first or not even with the 2 depriming sensors.
You can decap at 2400 rounds per hour and you barely need to be there for the process. I did all my brass in half an afternoon while I was working on my laptop a few months ago. I haven't gotten through it all yet.
