While still researching and shopping I've found Geist Werks Teardrops located in New London, Minnesota. I talked with the owner last week to get some basic info and he was very open to discussing TD's in general and what he's building. There is such a wealth of great info and a terrific community of owners, builders, and DIY'ers here that I was surprised not to see any mention of them. (I hope I've searched properly?) Does anyone have any experience with their work? They build two basic models and I'd like o consider the smaller "Phasma" model. Here's the link to their site.
