Chain seems to work well and is often cheaper, all else being about
equal. Screw seems to have the edge in durability and belt is quieter.
Today there are new drives out that have other attributes and some models of
one time are enough better that they out perform lesser models of a type
that in general would not be as good in a given area.
I like the screw drive and with the new quieter faster versions, I rate
it as top, also some of the most expensive.
Take a look at the Dwane Walton units for something different.
