I have a very simple solution to this significant problem: When a player raises the subject of buying a magic item on the open market I give a wry laugh and immediately draw four octopus cards for them to fight.

Seriously, the magic item level in TFT naturally sets itself quite low if you make people personally create the items they want. It is one thing to calculate the modest cost of creating a stone flesh ring; it is another to make a character capable and willing to do it.
