Tool heads--you want three of them. Keep the three tool heads assembled with all the dies and dispenser. Then you just need to pop in it in a new toolhead and maybe change the plate/primers, and that's it. You also will want the case feeder and the bullet holder and output bin. Definitely get a spare parts kit. I've had to replace a lot of things, all of which were in the spare part kit.
Then, for the other stuff, which is for general reloading, just pick what you can find at reasonable prices such as your tumbler, calipers, etc. etc.
