I have a Bernina 200E and I would like to start using embroidery to start a business but I am not sure if this is the machine to do it with. Can you give me your recommendations?
The motors, bearings, and other mechanisms in a commercial machine are designed for long-term heavy use. Those in home machines are not. A home machine may have a lifetime of 10,000,000 stitches, or even 20,000,000 stitches. A busy embroidery shop sew out 2,000,000 stitches per month!
On top of that, you'll also have speed issues. The time required to sew out a design with 6 colors and 6,000 stitches usually would be about 10 minutes. Unless you have a single needle machine -- because you'd then have to babysit the machine, changing colors every time you need a new color. With a commercial machine, you load up the colors once and sew out the design while you go do something else.
Here's a video you would benefit greatly from BEFORE you make expensive mistakes...
