Having used
@JCM-1 for distributing my much less ambitious hardware devices that are similarly much cheaper (percent wise) to make in bulk, I highly recommend partnering with him. He seems to have the logistics of selling and shipping things worked out much better than I would!
Also, it might be worth checking out
@ThisDoesNotCompute's post over on tinker different about his bulk SE/30 reloaded buy. It was a lot of work.
That said, I'm a huge fan of the ESProfiles and would certainly be interested in a group buy if you decide to go that route. Add me to the growing list of people committing to a buy. Although I'm think I saw you respond in the Youtube comments that you are considering trying to make one compatible with the Lisa case. I'd love to have a fallback plan if mine ever bites the dust, and also would love the performance improvements you've incorporated into the board.
Great work!
