Thanks a lot for the info, quite interesting. They seem to be even smaller height than the current revision.
I searched ebay but could not find any ... do you have a sample link?
The only problem is ebay is not really a reliable source. You may get bad parts that could fail later.
So for a prototype this is perfect, if it fails you just get another, but for me to resell these in a kit it's a big risk. Once soldered or packaged they are a pain to service.
