I got the RCBS kit, not the real expensive one with the Chargemaster, but the next one down. The only thing I got right away that was not in the kit was a powder trickler, and of course the dies and shell holder that I needed for the rounds I wanted to reload. I got it a year ago and have been happy with it, but I am still a novice. I am going to have to buy a case trimmer very soon. You will find that as you gain experience, there will be things you will want to purchase to make the process easier and more convenient.
I think that you are going to get a lot of opinions, as you always do when it comes to any discussion about different types of brands. From what I have read, I think it also comes down to what type of shooting you are going to do. I am quite happy with my RCBS cause I am happy with my 5 shot groups, even though they are not always dime sized. They are far better than I ever got with factory ammo. I'm happy, but I think there are better set ups than my standard press and standard dies for those wanting to do serious competition.
If you are going to do serious competition, then there are a lot of guys on this site that can give you very good advise. If you are an average shooting, like myself, then I think any of the kits that are made by any of the major manufacturers would do fine.
