Reloading shotshells for several different gauges?

[K98]

I have shotguns in various gauges. .410, 20 gauge, 12 gauge and 20 gauge.
I have a lee hand loader in 12 and 10 gauges but I'm thinking of doing it in a bigger way. Would I need to purchase 4 different presses or is there a better way?

It is possible to do it with just one loader and 4 die sets but depending on the loader it's not very convenient or easy. IIRC, the Posness Warren single-stage loaders work best with multiple die sets. The MEC loaders are a PITA to swap dies and for the price of the dies and the inconvenience of switching them most people just buy a separate loader for each gauge.
