You get what you pay for. 1 Tool head with your dies, powder drop all using hornady Lock Rings will do the trick. IMO once one starts using any progressive press, they eventually figure out what works best for them. I could get away with the lock rings, and did for a short time. That's till i was able to afford (or barter) for more tool heads.
If one has been working with a single stage. Utilizing a single tool head should not be an issue. Time consuming, yes. YMMV
