I’m not sure where you are in Canada, but there are several people who already have there Glowforges up there. They might be willing to show it off, if you ask. Not sure if this will help alleviate some of your grievances, but I do recommend seeing one in person if you never have.
They have said that they would sell laser tubes for replacement. I believe the repair center talk was just people volunteering to help other people out. For other components, I don’t think anyone has asked about purchasing them to repair their own unit. So that would be a question for @dan or @Rita.
