fwiw, the Cham is the only manual out there that is really engineered for this. M&R built it to handle roller frames in auto sizes and integrate with pre-reg systems. It's a sampling press, too heavy at the higher colors for most production runs and overbuilt overall.
I've been through a handful of presses over my career and none, despite what they might claim, are built to handle auto screens effectively. Other press brands can be used but require modification in my experience.
If you are going to get one, I recommend getting the highest color press you need right away to match your color capacity on the auto, minus the flash station of course. The duo-deck for the upper tier to make your 6 color a 10 or you 8 color a 14 is conceptually something you can upgrade later but the cost is actually prohibitive for that top tier in my opinion.
I'm still waiting for M&R to put an indexer on the Chameleon. Then it would be a serious sampling and production machine.
The only thing I really dislike about that press, aside from the weight is the micros but if you are already o.k. with that style from using your auto than that's a non-issue. I also do not care for the adjustable off-contact, it tends to cause more issues than it solves in the end but is also kinda handy at certain times as well.
