Well, I would suggest that before you buy any equipment you get a copy of The ABCs or Reloading. This book will not only tell you how to reload and why, but what equipment to use.
I started with 1 lb. of Bullseye, 200 generic .38 cal. bullets, 100 CCI SP primers, a mallet and a Lee Loader in .38 Special. I used this set-up for about a year to produce good, safe, accurate ammo shooting mebbe 250-300 rounds per month (depending on money in my pocket). When cash flow grew, so did my equipment inventory; first a Lee Challenger and dies and a scale. Now I'm up to 1 turret press, 3 single stage presses, 12 sets of dies, 4 scales, 3 powder measures, and about 1/2 ton of assorted tools. BTW I still own 6 Lee Loaders...
I don't like kits as I like to research each piece of equipment and buy the one best suited for my reloading needs, and I'm not stuck on one manufacturer. I have tools from RCBS, Lee, Lyman, Herters, Pacific, C-H and some I forgot right now. I chose the tools I needed not a salesman that put together a "kit".
I have never tried to "justify" my reloading by comparing component prices with factory ammo costs. I just like reloading.
