Also, the 1087 and the Leopold use the cherry stabilizers, and both have integrated 10key pad (activated by num lock).
FWIW, I can't speak for the Leopold directly, but between the 1087 and my filco, the cherry stabilizers make the large keys (return, shift, caps, etc..) feel dull when pressed (thud rather than clack), while the wire stabilizers on my filco make them feel and sound just like all of the other keys. To me, there is a clear difference but it is not undesirable, just different.
