I saw a video where a guy set up the Dillon swager where the shell flipped of the pin, hit a piece of cloth and fell in a container. Real slick like. I've got time so I'll probably get the RCBS press mounted swager.I kinda liked the idea of swaging and not removing material when i got started. But yet "forging" the material out.
Theres many good systems. I suggest (unfortunately) watching youtube videos. The dillon and RCBS bench top mounted ones i think are best. I have the rcbs one. I wish the end of the little stem (inside) was cushioned with like a urethane bumper. Nothing is ever perfect though if you ask me.
I set mine up with a small bungie cord so its basically spring loaded open. And i also put a small under the little cam pin to keep it from falling out. Kinda annoying design. Lots of adjustments but once setup correctly it seems to work great so far.
