It seems that Janome bought Elna some years ago. Now, a lot of sewing-machines from Elna and Janome seem to be identical, but they differ in price.
For example "Elna 864 air" and "Janome AirThread 2000D Professional" seem to be the same, at leats it seems to be the same housing. But "Elna 864 air" costs about 200€ more than "Janome AirThread 2000D Professional".
I cannot see any difference. Is there any difference that only experts can see? Is there any difference in quality and/or lifetime? For example, does one use plastic parts while the other uses steel parts?
