I JUST went through this and really dug deep into the available equipment and various kits. I researched the snot out this subject and can tell you what I found.
If youre looking for the most effective and inexpensive complate kit it is without question the Lyman Ultimate reloading Sytem on sale now for 699.00 at Cabela's. The ONLY item in this kit that will need to be replaced immediately is hand held primer. It sucks but one of the best replacements is the RCBS version.
The next best VALUE kit is the RCBS Rebel Plus Reloading Kit (sometimes marketed as the Rebel Master or Explorer Kit) . The single stage press in this kit is bullet proof and will produce some of the tightest tolerances and data of all the kits available, and the majority of single stage presses for that matter. I would also avoid and kit that includes a "beam" type weight scale. You'll be upgrading to a digital one in less than a week, trust me.
The rest of the kits are mostly Lee and Hornady and their versions. Nothing wrong with them, but their kits are typically not as equipped as the two above. And don't worry too much about dies. Most dies will fit other brand presses. For example Hornady bushings allow for die swaps between them and RCBS.
If you choose to buy one item at a time, choose a GOOD single stage press - I can't stress this enough. One of the absolute best performing single stage presses is the RCBS supreme. Try to find one on sale if you can. Then digital powder scale, a brass cleaner - stick with dry media as the tumblers and media are affordable. You can also use cat littler as dry media, much cheaper than crushed walnuts..ect. Lyman makes a pretty good hand held chamfer/deburring tool, brass trimmer, lube, manual, trickler, a few other small items and some bullets and brass, and you're ready to roll.
Lasty, if you hvaet already contacted this person to buy this kit ASAP, I would get on it....this is a VERY good deal. That press is almost $400 alone. Add a couple items and this is compete QAULITY gear. For real.
