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.
