Compared to the EV kit of the Constellation class (which is not cheap), the DFNM kit appears to be very expensive and quality-wise inferior. My impression is that the parts were hardly updated compared to Shapeways. There are only a few PE parts added.

90 $ without shipping and taxes is expensive. Compare that with the 1/350 kit: 150 $. Volume-wise the 1/350 kit is 8x bigger (800%), but costs only 1,66x more (166%).

For those outside the US, supporting US producers could hardly be an argument, given that producers and customers there are affected by such an ideology.
