It is more than worth it if you purchase your components in bulk. By that I mean minimum 2000 bullets, primers by the flat (5000) and powder in minimum of 8 pound containers.
I go through about 8000 to 9000 rounds a year, reloading even 9mm results in savings when you shoot that much.
Buying 100 bullets, 100 pieces of brass, 100 primers and 1 LB of powder is not the way to go.
