I agree KDK. Too much of a learning curve. Buy a single stage first. It may be all he needs. If not get the progressive later and use the single stage for low volume work or as a deprime station.
Make me agree #3 - for the majority of work, a single stage is best and RCBS makes excellent presses.. My Jr3 is still going strong after nearly 40 years of work..
For a beginner, stick to a single stage.. Once that's mastered you can go on to a progressive, but those work best for a caliber (or calibers) you're really going to reload in bulk.. Like 9mm, .45ACP or similar..
I have a Dillon 550 that I use for those reasons.. But to date, all my rifle reloading is done on the Jr3..
