Hi Dan, I haven't been able to find much information about that turbine or the other models that that Company makes.
I found two Companies that manufacture those turbines. The model numbers of the turbines are different but I am sure that the Companies are related.
This one is located in Taiwan:

The design appears to be good. I am working on building something similar to their 300 watt, but I want to do it using simple construction and common materials. I want the average DIY to be able to build them. As for how much they cost, you can try to contact the distributors and find out. If you find out, please let us know.
