Yes Steve - for most users I meant low-backlahs !
Actually, I expect zero-backlash in a rotary is achievable, by using two
separate worm gears and worm wheels.
This would mean it is truly zero-backlash, in all points, unless;
1. the stress is greater trhan the preload on the worm
2. and the stress is on the point where the worm wheel has an error
All worm have errors, its just a Q of how much.
