If I was going to do a full blown build I'd only consider some of the premium actions. For myself that would be a post ww1 oberndorf or one of the czech actions mentioned. Everything else will cost the same and starting with one of the "best" actions will be a small incremental cost in the overall project. I actually think starting with a pre 64 action would be cheaper in the long run than the run of the mill actions that require upgrades to the safety/trigger/bm, etc.
