Best “Cheaper” Arcade Trackball and Spinner Options?

Have an 8bitDo arcade stick, 8bitDo SN30 Pro’s and multiple NES/SNES controllers that I use with Batocera on an RPi3B+ running v40. Also wireless keyboard and wireless mouse dedicated to this setup.

Looking to add at least a trackball, ideally trackball and spinner to the setup mostly for occasional arcade use.

Has anyone gotten a trackball mouse like the Kensington Orbit to work properly? Wondering if I go that kind of route or just try to build a box that can sit next to the 8bitDo arcade stick. Something like a GRS trackball spinner combo on one USB cable, or two standalones.

Not looking to spend a ton, but realize there’s nothing “cheap” that’s really an option.
