Do static-dissipating mousepads actually work, or is there a cheaper fix?

A: They work, but grounding yourself is cheaper. Static cursor jumps are usually caused by you building up charge on carpet, not the pad. Touching a metal desk leg or lamp before using the mouse is a free fix. If you want the pad, brands like 3M and Kensington make them for $15–30, but don’t expect it to fix a problem that’s actually your socks and floor.
