Technicians in Germany charge 50€ an hour. If you need 5 hours for a foil, thats 250€ plus materials, rent, tools, R&D, insurance, and so on. There is a ton of health and safsty stuff involved. Breathing protection, first aid training, first aid materials, fire extinguishers, fire plans, two escape paths and so on. 19% is VAT. I think 1500€ for a carbon foil is reasonable.
I want to get a foil from China too.
