As it happens, I just called them. They can get it - for about £140 but haven't sold any in a very long time. That price probably has something to do with it.
They are about £50-60 in Japan (9000-10000 yen) so yeah, someone selling one for £24 is obviously selling a fake.
What do you get for that price? A higher quality unit, with a quiet fan and good filters. Should last many years. Also has fixing for an arm (also about £60) so you can have it over your bench. Not sure if the fakes have the fixing or not. It isn't cheap, that's for sure.
HAKKO priced it 12000 Yen = 92 Euro
of course we heard about cheaper price.
we sell it for 95 euro and we understand it is not cheap, tight marign on it.
I asked HAKKO why EU FA-400 is way more expensive, the reply is often the same: different power cord, electronic design and certifications.
we are sorry we can not provide a better price, maybe a small discount code for the forum. let me know if some one is interested.
