My impression is that you probably need to upgrade it a few times before it's really cost-effective, and that it seems to be aimed more at higher-level players who don't have much else to spend their resources on anymore.

I can see it being used if you're missing one particular material but have plenty of the others. If I had more resources on hand I would absolutely use it to get more Light Orbs, for example; I have 125 Stone (L) and no orbs whatsoever, and it is irritating.
