You can use a progressive press similar to a single stage. To do this you only put one case in and go through all the stations until you have a finished round.
This is exactly how I started. In fairness, when I started I was already 50 years old and most of my youthful impetuous nature has been worked out a while ago.
Another way of saying I had already done a lifetime of stupid things, and figure that my luck has probably run low...
As long as you pay attention, take one step at a time and don't get in a hurry, you can progress nicely and save yourself the time, expense and trouble of buying everything twice.
