I did some research out of curiosity just to see what's required for doing only the daily missions, then using the ships built for those on whatever missions come up.
I combined all the dependency trees for the ships, tech & buildings and organized them by Expedition tech level.
I don't know how to post a table, so you'll have to deal with an image!
If anyone has interest, I can do cost at each level also (how much would it cost to get to Expedition tech 3 & it's daily mission & associated payback)
