Agree with a lot of the above, and I only have a 550 set up for two different pistol calibers. Someone makes a light that drops into the open hole in the last die station that is pretty nice. I used an LED strip off another project and wired it up for free and it works the same. If you use CCI or Winchester primers where they are not stored sideways in the container, then I think you can save money on a primer flipper, as I've found that you can just flip the entire case over two times and it is faster than a flipper. If the primers come stacked sideways like Remington, then the flipper is worth it. It doesn't cost a lot either way.
