HQ items for leve turn-ins are great. One thing to keep in mind is that for company seals you can buy a manual that increases your crafting XP for 3 hours/20k XP, whichever comes first. If you know you're going to be crafting a bunch of stuff, those are great to have.

Also, I think it's somewhere in the 30s that the recipe for apple juice opens up, which is a recipe that doesn't need half a dozen materials, unlike most of the others.
