I use Lee Classic Loader kits in .38 spl., .45 Auto Rim, .223, .30-30, .30-06, and .303. I think they're great.
I did buy a scale when I started, checked my scooped loads, and have relied on the scoops ever since.
Agree that the Lee Modern Reloading book is a must...read it front to back, and then when you've been loading for a year, go back and read it again. You'll be amazed how much of it went over your head the first time. A lot of good sense.
Agree with getting the Lee Auto Prime hand priming tool. I never got comfortable with whacking primers.
Agree with getting a good caliper and a bullet-puller.
You'll need a case trimming tool, and a primer pocket cleaning tool, too.
One of the great advantages of the Classic Loader is you can fit your whole reloading setup into an ammo box. I take mine outside and load on my truck tailgate when the weather's nice, in a breeze under a shade tree when it's hot, down in the cellar when it's raining or snowing, and on the dining room table when my wife's working the evening shift at the hospital.
