I don't think going to 4-5 expos, showing off the machine, and answering questions via an interview is the definition of "hiding." I don't think they've disappeared. I think Kevin is in over his head with one major person in the team gone and trying to get production started while also going to shows (and even getting ragged on for not going to shows that he never said he'd be at) while also working a full time job. He's never been quick to reply to emails, and definitely needs a business-minded person to answer emails, field questions, do PR work, etc, but I don't think he's out to screw everyone over. He wouldn't have my $ if I thought that.
You, however, have come on here begging for a machine to the point of starting a thread trying to throw money at getting one, and then turned all sour grapes when you either couldn't afford one or couldn't quickly have one. I work in marketing too. I have a pretty good grasp of supply/demand, right/wrong, and the real world. Yes, things could be better and there should have been a video before the half payment was asked for. But to say that the only reason people are buying it is because it is rare is idiotic. People have played it, say it is fun, say it looks good, say the UV works in person, say the sound is great, etc. Obviously you haven't been reading the same posts as me, and just show up occasionally to sling some mud.
