Yeah, case prep is often the most time-consuming step. Fortunately, it only needs to be done once every several reloads. I find that I almost NEVER have to trim. I run new brass through the trimmer set to minimum specs. Neck-sizing only, I've never found any brass that needed re-trimming. Same with deburr/chamfer - once only. You don't need to chamfer again until you trim again, and I don't normally have to do that.
