What Carton Packer or Auto Packing is everyone using?

I am starting research into cartonizors and auto packing units for cans. At previous locations I have used Switchback's Brewpack Jr, but I wanted to see what people are using and enjoying. We are dealing with mostly 12oz 12pk, but would like a machine that offers flexibility if we were to expand packaing sizes in the future.

If you are willing to elaborate on aspects such as changing between sizes, maintenance (including daily cleaning aka washdown vs non washdown models), customer support, troubleshooting, efficency, date coding availability, or anything else you can think of it would be greatly appreciated!
