We have all RCBS. I started out with a Rock Chucker press and added to that one piece at a time. I went with a Chargemaster 1500 dispenser and scale next, Power case prep station, hand trimer which I added the power head to 2 months later. Next came a case vibrator and seperator for cleaning cases, hand primer and lots of misc. shell holders and other stuff.
This setup worked for about 2 years, at which time I added a Uniflow powder dispenser, A Turret Press with a second head. I just added a Hornady Sonic Cleaner for cleaning dies and gun parts, I don't like using the sonic cleaner for brass since it seems to take awhile for brass to dry.
I have been lucky that my son and I have split the cost of this hobby. Shop around and see what fits your needs, A kit is a good way to start out, whatever you think this startup will cost, multiply it by 2 times for all the extras. Good Luck,----Riflemann
