very true , also consider this , if you where to ask me to make you something similer with the fit and finish and complexity of these devices ( back in the day when I had some nice machinery at hand ) I would charge you at least 10 x more then what IMEO sells them for . Sounds very expensive true , but CNC's are insanely expensive machines .I'm surprised China isn't already making copies without your blessing. I think your prices don't leave them enough room to do it. They have to be going crazy seeing what used ones go for, and trying figure out how they can get a piece of the action. Without the quality and customer service in the equation, theyll never figure it out.
On the other hand , most Chinese things are all about making a quick buck ( not quality goods ) and the EGO market is just perfect for that
