I agree, a good trackball reduces the wrist strain and the possibility of carpal tunnel syndrome. I have been using a Logitech "Trackman Marble FX" for the last 6 or 7 years. This particular model has a 2" ball which gives the much needed resolution for cad and image editing. It is a shame that Logitech does not manufacture this model any more. I also use a Wacon tablet.
