The best by far Track ball out there has not been manufactured since the late 90's, but can still be found on E-bay at a hefty price. Like stated earlier you need to try one first, i would not work with out one, so i have bought a couple of back-up's. i bought my first one back in the early 90's new for around $60, now on E-Bay for up to $200. if you look hard and are patient you can get for about $100 unless i decide to get another one and see it first. Only comes as a righty.

Trackman Marbell FX with the green connector only, and not the gray connector.
Never understood the concept of a wireless trackball, as it does not need to move so why care about a wire? Wireless mice make total sense to me. I tried it but just did not feel the same original has a transitional blend to the desktop, therefore i"I'm going to be willing to pay the higher price for the used version. Still own 3 have owned 6. One day i may have to buy it though.

Main reason i have my track ball is for my wrist, when i did contract work i did leave a couple of jobs because they would not let me use it. We had to use company provided equipment, i would start to feel some twist or pain and that was the end i left. After a while i would not take a job if they would not let me use my track ball. Started CAD in late 80's and i still have no wrist, shoulder pain and plan on keeping it that way. I also use a Space Pilot and before that a Space Ball. Don't leave home without them!
