The 5 series is where sewing starts to get serious for Bernina and the 530 is the entry level machine in the series.
395 stitches with the ability to fully control stitch width and length as well as choose one of 11 needle positions gives ambitious sewers perfect stitch control. The buttonhole feature is excellent although you have to go higher in the 5-series range (e.g. the Bernina 570) for the automatic button length measuring.
The amazing Bernina Stitch Regulator (BSR) can be added as an optional extra.
You can see more details about the 530 on the Bernina web site.
Delivery is usually within 2-3 days and all machines come with a free 1-hour lesson.
