The Viking Sapphire is a GREAT machine.
There are many great machine makers on the market.
Viking is one of them. I have upgraded through 4 machine levels with Viking and Sapphire was my favorite computer-aided machine.
It never went into the shop for repairs or fixing.
I sew daily. I sewed every kind of fabric and project on a Viking Daisy for five years before I even took it in for a tune-up. I only tuned it up to trade it in for the computer gizmo bells and whistles machine.
I have done extensive sewing with Kenmore, Janome, White and Viking machines. They all have their good points.
Every machine that is badly used can be made to go in for repairs often. Please keep that in mind.
