Wow.. I started this thread over two and a half years ago. Glad to see that the following and owners of these printers has multiplied so much. I don't feel quite so alone now.
I still have my original Qidi Tech model printer and it still prints great. I'm having a scrambled LCD issue now but just emailed Qidi and hopefully they will help me fix the problem. When I bought mine back in Aug 2015 it was one of the best deals I could find for a 3d printer with similar options and features. I must admit it's proven to be a well made and the company has been great with support and help. I haven't kept up with the new models but hope that's still the case. The new x-pro model with the touchscreen and the breakpoint and removable plate sure looks nice.
Maybe it's time to save up for a newer model!
