Ok, I bought the one from Ebay, although instead of the black one I decided for the silver one.

It arrived very quickly (~5 or 6 days), very nice packing and good quality. In general I think it is a very good value.

It is very lightweight and it fits confortable in my pants pockets, although I haven't tested it with denim jeans and I remember that the N810 was a little tight there.

To clarify it does not come with any belt clip, and I think they have updated the ebay page.

It comes with the plastic protection for the screen but not for the camera, no big deal.
