External Trackpoint

[OldManClayton]

Sis is getting an Ideapad s10. She's always liked her thinkpad 560's trackpoint and I'm looking into finding a solution. I know there are keyboards with them and those scrollpoint mice, but I'm looking for something a bit different. Is there anywhere you can get external trackpoints (or pointing sticks or touchstyks or whatever) either by themselves or embedded in a mouse shape? Not talking about the scrollpoint, the buttons aren't in the right place to be used with the trackpoint as a cursor.
