Dude...there was more than enough interest when you did this the first time. You should figure out all of your logistical issues and THEN post up a group buy post. People are going to be turned away when 1. There isn't even a prototype to be displayed and 2. You don't post a potential price. We all know that there is a demand, all that there is left is for someone to supply it with a quality product. Can you do that? If so, get going on it. I will say I am interested when you figure out all of your details and then post them up on here. People need more info before they are going to commit to buying anything.
