Pixhawk - Purchase

Hello Guys!

Im quite new to community, and in the past I’ve built several drones based on closed hardware like Holybro Kakute and others. Now Im looking for something more “professional” like Cube pilot
So I have question to you , if you have some pilots which are not used and you want to sell let me know.
Im looking for some used orange pilot set. Or maybe you have other ideas how to built more professional drone not paying to much for first time.
I live in Poland ( European union ) so Europe would be preferable due to shipment issues.
