I think that as westerner's we are spoiled when it comes to exact specifications of anything even remotely touching a custom order or even a regular order, we order something and expect to be exactly as we see in pictures, no deviations of any kind and when things are coming off an assembly line this can be held true for the most part but handmade things are a whole different animal, especially from a country like Nepal.
And as with anything spoiled it can be rotten(as Karda said people being rude/demanding/nasty/insulting). This is a sorry truth, it's especially disheartening that it happens to such a wonderful woman as Yangdu who is always giving her all or to the especially hardworking Karda. All I can say is you both are very greatly appreciated and looked up to and I thank you as I'm sure countless people have.
As far as my own order goes I saw it as more of a favor from Yangdu, bear in mind I didn't pay anything extra for my "special" order, I just asked if I could get something close to my said specs and Yangdu said it would be possible and made me feel elated. I did not feel in anything truly negative when I received and opened up my m43, I knew I would be taken care of, I have no worries.
If special orders are causing such wonderful people anything detrimental then by all means get rid of it, you will still have droves of loyal customers buying up all the beautiful works you produce.
Personally I'm sure you could resell any order at full price and people would still buy it. Especially the M43 model which everyone seems to love, have the kami's make a few and they will sell faster than you can say done deal, I guarantee it.
All that being said whatever happens, whether special orders are scrapped or not, I just hope I'll be able to get something a little closer to what I had in mind in the end, a lighter M43 is my dream, regardless I will always support HI.
