Cheapest is a Lee Loader for about $25. There has been a lot of discussion of the merits (acceptable to good quality ammo) and disadvantages (slow rate) on this site. You also should invest in a good manual (I happen to like the Speer, Hornady and Lyman have good ones too). Read the manual & don't cut corners for safety's sake. If you like reloading you will soon move up to a press & regular dies, powder balance, case trimmer, dial caliper etc. Good luck. Revisit this site with specific questions about favorite loads & powder/bullet preferences. If you are careful you will find that your reloads shoot better than most factory ammo.
