Non twink enchanter spell and gear questions.

[Parthais]

So I recently hit lvl 12 finished my stein of Moggok quest and pick up a crude stein during. I am currently doing even lvls solo and odd lvls in a group to learn both mechanics. I like to purchase the next set of spells before I hit the lvl so I can spend any extra money on gear. Does anyone have a link to the total cost of chanter spells per lvl?
I've been told to just save all money until high levels to buy expensive gear, but is there any gear I can purchase around my lvl that would be worthwhile to purchase?
Thanks in advance!
