For those who buy dies off the shelf, Hornady is hard to beat. They're not really expensive, they're well made and thought out, and they're easy to get upgrades for (such as micrometer bullet seater and match bullet seater insert).
Most of my resizing is done with Forster FL competition dies (all custom honed). For bullet seating, I like the Redding Competition micrometer type seaters, also have this same setup in a Forster and it's just as nice. Recently picked up a Redding Type S bushing FL sizer for my Ultra and looking forward to giving that a try.
When I first started handloading I used all RCBS, but for my recent rifles have switched to Hornady because I like the fact that I can easily adjust the bullet seating depth on the seater die with a twist of the finger without getting out tools to make that adjustment. I've tried redding, but I had bad luck with a specific die so gave up on them and stuck with Hornady, but love the rest of redding's products such as their presses.
You send Jim 10 pieces of brass fired 3x and he hones the die to fit the perfect sizing.
Neil Jones basically same thing. He builds a NS die off your reamer print, you fire the brass 3x, return the NS die to him with the brass and he puts a perfect fitted body insert into the die to become a FL shoulder bushing die.
