Buy what ever you want. I wouldn't buy the square deal because it is tiny and I have big fat fingers. A coworker has one and I didn't like it. Of course I have been using the Dillon 550 and 650 So that is what I am used to.
When I bought my first 550 I was going to get the square deal as it is cheaper and I only intended to load 40 sw. Next thing you know I bought a 9mm. Blink twice and I added 223 to the mix. Had I bought the square deal I would not have been able to reload for my 223, 30-30, 30-06. So I would suggest to look hard at the 550 first. But if you are sure you are only going to reload the 9mm then the square deal could be the best answer but I doubt it.
When dealing with Democrats, let us remember we are
not dealing with creatures of logic. We are dealing with
creatures of emotion, creatures bristling with prejudices
and motivated by pride and vanity.
