Get the 1050!
I started shooting uspsa with a 550b and used that to load for 6 years. I have no idea how many rounds I loaded on it, easily 100k or more. After I really stepped up my shooting and got busier with life I decided to buy a 650 with a case feeder and bullet feeder and instantly regretted waiting so long, it was a huge difference. Then I took the plunge into open with 9major and decided I wanted the swagger and primer seater system to dial in my loads. I picked up a 1050 and all I can say is WOW!
When I started I read all the posts about just buy the 1050 and always rationalized not spending the money but now that I took the journey through all 3, I really wish I could go back and listen in the first place.
