I have a spare one but she has a little mane trim unfortunately, honey! If you want a place holder let me know and I shall send her your way.
The red one turns up much less often than the pink one. If you keep an eye on European/Aus ebays she shows up reasonably often. She used to be a relatively inexpensive pony but she has really recently bumped up significantly in value. I would say $18-20 for the pink if she is working and double that for the red.
