Magician Gear - Bang for Buck!

[Deliverator]

So I'm trying to figure out what to chase for leveling a mage. I have a level 17 magician that I'm playing now and I'm trying to make sure I'm spending my plat effectively for the long haul rather than buying replacement pieces as I go.

I'm looking for the best bang for my buck and I'm looking for relatively low cost items here, 5k max and preferably things I can resell in the future when I have replaced it with better.

(I already have my early focus items)
