My 12yo has been happy with her Mizuno GXS100. It is designed for smaller hands.

If I understood OP's question correctly, the one brand I would tend NOT to recommend for a USED glove would be Mizuno.
The gxs5x's and gxs9x's are game-ready lines, and by the time the original owner parts with one, it's usually a floppy mess.
Mizuno's - GX93 is a fantastic glove (it catches EVERYTHING) and so are most of their models. You can even their higher end models for sub $100 from places like SoftballSavings and BallGloveWarehouse.
GXS92 is a popular choice, the only 93 I see is a baseball mitt, so I'm pretty sure you're looking at the right thing.Is the GXS92 the same mitt by chance?
