Kensington Orbit Optical Trackball Mouse, USB 2.0, Left/Right Hand Use, Black/Silver

Bottom line: The Kensington Orbit Optical Trackball Mouse ($35.00 on Amazon as of 2026-10-06): Optical tracking with a 40mm perfect-sphere ball for precise cursor control; main trade-off: only two buttons, so no dedicated scroll wheel or thumb buttons.
