Speak to me of mice. Mouses. Whatever.

I am in need of a new mouse; current one (evoluent vertical) is dying and also ergonomically bad for me (yes it's an ergonomic mouse, but I'm a special snowflake).

What I need:
* because of mobility restrictions, I'm looking at things that don't move -- so trackballs or joysticks. Small touchpads might work, I don't know.
* because same, dual-hand or lefthanded
* scroll wheel preferred but not required (current mouse's scroll hasn't worked for two years
* PC running Windows 10.

Anyone have suggestions, recommendations, anti-recs, advices, etc?
