I've actually discovered another source for them... I'm calling them a "V3" for lack of a better term. They don't require heat extraction, just unsoldering from PCB. There is some thermal paste on them which wipes off easily. These diodes seem to have better and more uniform beams since I believe there is some warping to the die from the extreme heat needed to extract them from the NUBM44 blocks. There seems to be a decent supply of them for now which is why I haven't had to increase my prices.
