I am sort of prejudiced against the Square Deal because it uses a non-standard set of dies.
OTOH, a fellow I knew who did small scale commercial reloading had 4 or 5 of them set up in his basement and never had much in the way of trouble with them. He ran one of them for 2 or 3 hours, 6 or 7 days a week. He pumped out boxes of reloads at an amazing pace. He had a pretty well though out setup and was probably doing 8-10 boxes of reloads per hour.
When he first told me what he was doing, I thought he was nuts, but, he had a pretty good little side business going. He also cast his own bullets, so there was additional time going on there, but he got the lead for free somewhere. This was back in the mid-80s, so a fifteen hour a week job that netted him a couple hundred bucks a week was more impressive then the same numbers today.
He told me he only had about $1500 sunk into the whole reloading/casting setup.
At one time he told me he was making almost as much just selling the cast bullets, as from the reloads. Guess when the raw material is free, it is tough to lose money on such a deal.
