WTF? Really? They are asking that much?
I know the nozzle is not the cheapest piece to make. Actually, it's one of the more expensive mechanical parts in the machine, due to low tolerances and complex machining. And spare-parts never have been really cheap. But this is nuts. You can almost have one printed in silver at shapeways for that price. Hell, you could print them in brass for that price at shapeways.
(I'm not allowed to say anything about actual production prices, or markups. Not that I know. But if I where allowed to say something and I was to do a guess, I would say 5-8x markup. But, I'm not allowed to say anything, so I say nothing)
Shipping always has been a problem. I know they tried cheaper options, but then shipments where getting lost, causing other problems. IMHO, they should drop-ship a whole bunch of spare-parts to the US and then you can ship them cheap, piece by piece from there. Logistics on that is harder, but not impossible.
