Significant quality difference in keyboards?

I am about to order a localized keyboard for my x200 that is being imported from the US

So I looked in the Hardware Maintenance Manual for the X200

... and found that there seems to be two different keyboards for each language (they have each one column on page 136 in the manual).

When I loaded up both keyboards in my shopping cart at IBM/Lenovo, there was a significant price difference between the keyboards. The keyboard in the right hand column was double the cost!

I do realize that companies sometimes have funny (not logical) pricing of their products but such big price difference makes me suspect that there is a significant difference in the quality of the keyboards.

Does anyone know what the difference is between the two keyboard columns and if the keyboards in the right column are worth double the price?

Ok, some research of my indicates that the left column consists of keyboards from Chicony and the right column consists of keyboards from NMB.

Why would an NMB keyboard be twice the price of a Chicony keyboard? Is it that much better?
