Which manufacturers who make BadUSB possible on their drives?

So as we all know by know BadUSB is possible on Phison 2251-03 chips. But are there any more reflashable devices in the wild that could be dangerous? And if there are is the firmware easily changed or does it require OEM tools?

I'm asking about this because I have once, when broken my USB stick, stumbled upon a Chinese manufacturer flashing tools and although i couldn't understand how to actually do it I'd guess some people could actually make it work.
