Thank you Harley997... It's a lot of money!
I'm really surprised because blackminer (or black electronics, if you prefer) had partecipated to the CEBIT EXPO with a lot of new machines, and in particular with scrypt miners...
Damn... they are too in late... I payed my machines in march and they had promised me to deliver my machines in april...

 

I hope at least to receive my moneys back !
