I certainly agree with the value of using quality designs and properly
maintaining / servicing a machine .... regardless of which brand of
machine is used.
When I look at a machine with manual tensioning and then look at what it
takes to tension threads on the Amaya ..... I have to admit, that I
question whether I want that much technology ??? I know with my current
manual tension machine, I almost never have a thread break and if I do,
generally the needle needs replacing. Yet it seems to be common in this
group for operators to report thread breaks on the Amaya ... and that is
why I am wondering if I would be disappointed with the auto tensioning
of the Amaya ?
Anyway, thanks for the info and have a great evening.
