Get a Dillon 650 and get the best of all worlds. Initial cost is a little higher, but you're making a once in a lifetime investment.
Once you get the Dillon 650, you're done. You'll never have to invest in another reloading machine, and even if you load 100,000 rounds per year, you'll still have a machine that you can pass on to your children and they can pass on to their children.
The best always costs more in the beginning, but ends up being the most economical in the long run.
If you think a mighty military force is expensive, wait 'til you see what a weak one costs.
