The deal with the ULA Amigo Pro is that the person who designed it had a "handshake" agreement with Brian to make it. The designer did not want to continue the agreement with the new owners of ULA. This per an email I received from Casey of ULA in November.

I hope that means that the designer will start making these filters on his own, but I'm not holding my breath.
