Well, with the crafted items there's nothing you can do except make them yourself or buy them. Or ask a friend to make them. So... it just depends which is most feasible for you. How much are they on your server?

Personally I didn't really do any Alex (just got one item via Alex I think), and I just completed my anima last night. All items acquired from daily poetics roulettes (main + 50s) and BTs (sylph, kobold and amaljaa).

If you don't mind hunts, those are a really good option.

But really, just chip away at it slowly. No need to rush if you don't want to. If you have a tank levelled, doing daily roulettes as the adventurer in need is a steady way to make decent gil.
