I guessed 
usually the “standard” (black, ss) colors run out first. If I absolutely needed a B80, I would look into how much it costs to 3D print the front and back plates + components/magnets, because then the black frame is the main thing (see e.g. nebula sparkle) and I’d even get a custom AIO out of it. If, however, full compatibility is what matters, meaning every Boro RBA works in it, then the Blaze is also a good choice. But the B80’s “interesting” positive pin layout was already changed in the G80S to be fully Boro compatible.
