I have never purchased a Luma product yet, and I have never seen one in real life. Everything I know about it is from this forum, the Luma website and other reviews of their product on the web.
I am struck by the innovative design and the uncompromising attention to detail that Greg is describing here even to the short-term detriment of his bottom line. It is truly remarkable IMO - surely the pressure to put a product out even if every component was not perfect must be great, and many a lesser company would have succumbed to it. Plus the fact that it is made stateside (in my hometown too...) is making this upcoming purchase a no-brainer for me.
