WTB Fightstick for Child: Qanba Drone (maybe Fightstick Alpha)

I’m looking for a cheap, smaller form factor Fightstick for a child to be able to grow into. She is currently 4 years old but proper execution really doesn’t matter right now.

However, I would LIKE to be able to change out the buttons with more colorful alternatives and possibly be able to do an art mod that’s child-like and eye popping (this is why the Drone seems most appealing and I don’t want the Hori Fightstick Mini).

I’d like to be able to buy one for no more than $50 shipped unless it’s already colorful and customized.
