servo continuous rotation Q

i cannot find the right link any longer.
what brands of (cheap, ordinary) servos are easiest to modify for continuous rotation?
i remember that one popular brand was difficult to modify and i'd rather avoid trying out that particular sort.

Among the easiest: Futaba S-148, Hitech HS-422, most any standard-size servo from Grand Wing (GWS).
