I didn't mean to question you. Keyboards on Taobao often come from a big pile of electronics waste shipped from the US for scavenging so the condition is a bit unpredictable. (However there's much less competition on Taobao for the rare stuff like Model F AT.) A Model M can be bought in excellent condition for around $30 in the US so I totally understand why you'd want to buy from overseas.
I have read the term “foreign trash” in some mainland Chinese forums, but I had no clue what it exactly mean, so thanks so much for your explanation. Indeed, as production of M has stopped for quite a long time, scavenging a good one is not easy, not even at ebay. It requires knowledge of the product and immense amount of luck, but I am still learning. When I’m familiar with necessary knowledge about it one day, I will try to look for it from Taobao.
PS, I can’t live without Taobao nowadays, and they are no longer just selling some knockoff now. One of my Realforce 23s was bought there.
The IBM Models on Taobao are usually been used for a long time and there might been some dirty water from the rabbish. So I got a Model M NIB with a fairly high price as one of my collection.
I have to admit that quality of goods there is still an issue sometimes. But just like the name of Taobao in Chinese – scavenging, which is always not an easy task and can be risky sometimes

The left one is bought from Japan, the right one is from Taobao, can you see the difference?
