A few thoughts:  One of the designers at my place of employment used a
thumb ball from Logitech, and swore by it, but one time I attempted to
modify a small part of a drawing using that thumb-ball, and it drove
me crazy!  And I am a track-ball user from the get-go. I originally had
a very expensive one, that had three useful buttons--perfect for Linux--
but it eventually wore out, and the replacement was out-of-sight,
price-wise. There was some other tracker for a while, but not very
good--it was mechanical. Then I discovered Kensington. Their Orbit
Optical trackball sells for the same price as the Logitech
unit on the right in the illustration at the website above. I haven't
used the Logitech, but I have 3 of the Kensingtons--one for each
desktop and one for the laptop, which I carry with me if I need the
laptop. BTW, I don't consider the Logitech unit a palm ball--it's a
fingertip ball, like the Kensington.
But if you're into thumb-balls, it looks to me like the wireless unit
pictured on the left is a thumb-ball.
One other thing: I suspect that like the Kensington, the Logitech ball
is not captured, and will fall out if you upset the base. At one
point, I actually thought I had lost the ball! Took some real heavy
searching to find it!

Here's the Kensington link:
