It sounds like you load a variety of cartridges if you have a lot of cases the bigger progressives might be the way to go if you can load enough of each cartridge that you don't spend more time in setup than you do loading.
If you load smaller batches of 200 to 500 I personally prefer (in addition to your single stage) the Lee classic turret probably the fastest press to change calibers on and still load 100 to 200 rounds an hour . And or a base model progressive cheap way in is the Lee auto breech lock pro , or the better built Dillon 550 .
A lot of this will depend on your budget for equipment . Before you buy look at cost to set up your machine for all the cartridges you want to load on it.
This is actually a good time to be a reloader or will be if we get past all the shortages , we have a wide range of equipment to fit many needs and budgets available.
