General   (General discussion, talk about anything.)

Tonker. It is a very good sewing machine but as you said industrial.
It isn't much use to someone who is creating craft items.
Domestic machines are multi purpose and do far more than lockstitch.
That machine you have for sale is the workhorse of the sewing industry and no fashion, household, car interior etc could be put together without one.
There are a myriad of specialised industrial machines that do a lot of other fancy things but the domestic sewing machine has them all rolled into one.
