I searched for these spindles and now I'm so confused...

solar.jean states on a few of his listings "FOUR BEARING"; first written only on the listing image for a spindle alone with "Japanese Imported Bearing" and second only in the listing title for the £252 spindle+VFD with "Germany Imported Bearing"

As I buy the ballscrews from linearmotionbearings2008 I saw that he also sells spindles which are far more expensive (£353). As I asked him if he can justify the higher price, he only made a "best special price" which is still £36 higher. The only important difference in the description is that he claim to professionally test them before shipping.

Now my dilemma comes from the fact that he already sold 54 of them at this very high price. And 54 are a lot!

I even read somewhere on the forums that the German bearings are actually made by a Chinese company named "German" and the Japanese ones are top brands but that specific model number is supplied only to China.
