unless you have a LOT of capital to outlay then its not going to be worth it..Dependant on which elements also as they will possibly need to make the set up for you at a cost of approx £10000 each one..ive already gone down that road and dropped it and found a better source closer and far more reliable in the quality.
There must be a nimber of manufacturer based in china that are already producing elements.
Europarts buy there own element from china, often they are better quality than the genuine elements. example genuine Creda 10in fan els and their j shaped grill els are made using very poor steel, they buckle/split within a couple of years.
Qualtex seem to have there own elements manufactured but they are poor quality compared to the Europart pattern els (in my opinion).
