Yotesnuffer,, The progressive set ups are nice, once that you get everything adjusted properly, but they can be really frustrating until you do... If you need to change components within the same caliber, then you usually need to start all over again...
My only advice for someone starting out would be to buy an "O" type press, as opposed to a "C" type, if you are planning to load the heavy magnum type rifle/pistol rounds as they require quite a bit more pressure at times to resize cases...For the smaller cases, either will probably last your lifetime, as long as you maintain it on a regular basis..
The prepackaged kits are great, and usually contain most of what you will need, you can always upgrade individual items as time and experience builds...sometimes you can find high quality parts in pawn shops and yard sales, where someone has died, or just stopped reloading for whatever reason...
If you belong to a hunting or shooting club/range, you can also upgrade by letting other members know you are starting out... Our benchrest club has a 'swap' meet twice each year and once in awhile there is some really good stuff at more than reasonable prices...
