A quality machine like the Dillon will last a lifetime. Every time In my 61 years that I bought "cheap" I regretted it sooner or later.
My life experiences have convinced me that the most expensive item is usually the cheapest in the long run.
Having said that, I would also recommend that you gat a single stage press to start with. Learn the reloading hobby one round at a time, and when you've been reloading satisfactory ammo for a year, then get a Dillon.
Believe me, you'll still use that single stage quite a bit even after you get the progressive.
If you think a mighty military force is expensive, wait 'til you see what a weak one costs.
