As you can see, there are many opinions. What is true is that safety is of paramount importance. I'm sure that there is consensus that case length is an important issue. No matter what you use to reload your shells, you'll need something to ensure proper case length. The Lee loader and a simple case trimmer is sufficient to load safely. You can spend $250 getting rigged with a bunch of "quality" equipment to load your shells, but......
Bottom line, you'll still need a dial caliper and something to trim cases.
So, you can spend $20 on a Lee loader and between $15 and $40 more to trim cases, or you can spend $250 (which if you decide you love it, you can get over time as you need it), plus the same $15 to $40 bucks for a case trimmer.
I've given you a couple of options that will do the job well, and are affordable. Start small, learn the process and see if you like it, and move forward from there.
