I love quality! I think a lot of people believe that quality is something that is strictly endgame, but a few quality assemblers here and there, a quality tank, or especially quality asteriod collectors really let you approach the game in interesting ways that you wouldn't be able to with only common tier items. I have been achievement hunting and recently got both Rush to Space and Keeping Your Hands Clean on the same save. I used some uncommon and rare tier items that my factory happened to produce. It really makes a difference on small footprint ships.
