It sucks if you canceled another order and waited for these boards based on the projection that they would be cheaper, but unless you were *guaranteed* that these boards would cost 470, not sure what recourse you'd really have. This is the exact reason I don't invest anything in Bitcoin/preorders/ASICs that I'm not willing to lose.
Well i am aware that i wasn't guaranteed that price, but i just trusted burnin. He was usually a man of word and he never said anything about the price going up for this boards and cryptx kept it secret until he opened his store (no idea what's the logic there). I already said that i'm ok with the loss and will try to minimize it and i will move on. I don't have a grudge against anyone.
Burnin actually just emailed me that he doesn't have anything to do with the final pricing of these boards. He stated in another thread that the price rose somewhat (more parts etc) and that he takes a reasonable margin on his work (whatever that is).
We know the chips cost 360 euros per board, so that means there's already 110 euro reserved for parts and labour, design etc. Increase that by maybe 30 euro for reasonable amount, and we'd get about 500 euro for a board from burnin directly. The BitBurner XX assembly etc cost about 100 euro so I don't think I'm that far off with 140 euro for parts, labour etc.
Now you can decide for yourselves if 200 euros for distributor is a reasonable amount. An increase of 40%, and 43% more than I estimate burnin charges for his parts and labour.
