You do not need an AOL gauge or comparator to begin with. They may help you later. I make really accurate loads and never use mine any more. The RCBS dies are just fine. The Lee's are just fine. You have die snobs that swear you need to spend $200 on some. The cheap ones work just as good and you can always buy whatever later.
As far as trimmers, the cheap Lee ones work good. I still use them for some Calibers. You can always upgrade as you see fit. For my ARs I use the WCT.
For a primer pocket cleaner I have a Lee but don't even know the last time I used it. If I need to I use a flat head. You don't need a tumbler. Dirty brass shoots just as good as clean brass.
I use a cheap plastic funnel. Hornady Unique Case Lube is outstanding. A caliper comes in handy. I have a Cabela's brand.
People will try to pressure you into buying things that you don't really need. Not everybody can afford it. I would stick to the basics to begin with and you can always upgrade slowly as you want or need. This can be a REALLY expensive hobby but doesn't need to be. You can spend a lot of money but don't necessarily need to all at once.
