The Speedy Gonzales Club!

I'm thinking I'd like to find a gently used Murakami Cherries Speedy 25. Does anyone have a good recommendation as to the more reputable sites and/or most likely to find one in better condition? I might be willing to replace the leather as long as the canvas and interior are in good shape - but really the concern is authenticity. I've read on various threads that even Fashionphile and RealReal have recently sold fakes.

This would be my first Speedy and first pre-owned purchase so any/all recommendations are welcome! Thanks :flowers:
