Just build one yourself... It's quite simple and a lot cheaper. All the components you need are open source. Open hardware and software. When something inevitably breaks you know what exactly to replace.

If you don't mind paying a little more and want a ready to fly / kit versions: pick any of these. I remember the Holybro x500 kit used to be very popular (review: https://m.youtube.com/watch?v=cTVtFYONHiY )

You can control them using mavlink / mavsdk etc... the python libraries are good enough.
