Al,
if you do contact Craig just be mindful that the cicada driver thing is a sore subject with him. When I spoke with Craig ages ago, he had mentioned he had a deal with NP, some kind of mutual agreement of purchase of said drivers, but NP had asked Craig the manufacturing source of the drivers (China) of which Craig had shared with him (before actual purchase agreement was settled). I believe at said supposed meeting, Craig was left empty handed as NP didn’t show up (I can confirm that when I asked NP for drivers they were brand new, he must have had some built through the original manufacturer). Craig isn’t a fan last time I checked
