One question

what makes this device so expensive please?

I see a normal cheap chinese Navigation device with no additional
gear.
Also if this is additional gear it will cost about 10$

So lets calculate

Cheap chinese Navigation device : 60-100$
Additional Gear : 10$
Software : 0$ (XCSoar and LK8000) is FREEWARE

There are many different options out there for "cheap chinese
navigators" I chose what I consider to be the best value and
performance.
Then you have configuration setup and support.

Sure anyone can put together the same solution however there are a lot
of pilots out there who want something that is easy to use and works
out the box in their region configured for their glider.

You should ask the other vendors selling similar products at over 2
times the price the same question.
