Well, it depends on what it is. Using Restricted Gear to get something at the level you eventually want it, rather than starting with a a version you have to toss, makes sense if the thing you have to toss costs 25000Y or more.

Which is, you must admit, rather rare.

Mage Foci come to mind. Not only are they expensive, but you're quite limited in Force with 12 availability, and the bonding cost are better at character creation.
