200% is still fair imho if you think about development costs.
We're talking more in the 400-500% region. A lot of this is eaten by the arrogant dealership. It can happen that you want to buy an EVEREST 2 but can't hear it first because the dealer is simply too lazy to unpack them. It really happened here!
Not to speak about margins in the cable sector. 4 digits percentage should be normal there. Or how much RMB do you think the chinese "high end" cable assemblers take home a month?
