I've contacted the seller via SMS and got his reply. He told me his taobao account that your agent contacted is already stop to use.
His current taobao account is as follow.
also he told me item is still avairable.
My 2931 was just broken last week and I am afraid that it's the flyback issue. I just asked the seller to put the item on-shelf, therefore we will be able to purchase.
here is the link: item.taobao.com/item.htm?spm=a…979186324&_u=k1tabu1nde33
I already bought one. just FYI
