I actually built mine, with the help of what used to be the MN Mill. They went under not long after you posted this.
I dont check these forums as often as I should. HAHA
I'm really glad I paid for the class to build one. They led me through the steps of building it, and supplied all the parts. I left with a fully functional printer and the basic know how on how to work it. If I didnt have the class I dont think I would be printing today. I had no knowledge of anything related to 3d printing, other than the idea of "I really want to do that"
I wish there was a more active group here in the cities. I think it would be cool to meet up once a month and BS and show off what we have made.
