If you're a trackball person, a lot of trackballs have a scroll ring that's similar to a click wheel. The Ploopy A+ has two discrete scroll wheels: https://ploopy.co/aplus/

I'm pretty partial to the Kensington Slimblade though. You scroll by twisting the ball itself - very satisfying once you figure out the technique. I hate the aesthetics (it looks kind of tacky) and the client software (bloated and buggy) but it's the only trackball I know of with this feature and I like it enough to put up with the issues. https://www.kensington.com/p/products/electronic-control-sol...
