Much of the answer will depend on how many rounds you intend to reload. If your like me and load 1000s of rounds per year you might want avoid hand trimming and prep. After sizing I trim .308 and .223 with Little Crow Gunworks trimmers in a drill press, they're fast and accurate. For the final prep I use a Lyman case prep xpress for removing the crimps, Chamfering, reaming and primer pocket cleaning.
These tools are not cheap but you wanted a cry once option...LOL.
