The people I was talking about were discussing Bernina home models, not semi-industrials. People I know who are unimpressed by Berninas say the company is superior at marketing. I can't get over how much more expensive Bernina home sewing machine feet are compared with those for industrials.
I live in New York and have access to a shop that makes buttonholes for a reasonable price. Sample makers for places like Marc Jacobs take their stuff there. Unless I have an emergency, I'm going to continue having my buttonholes done there. I have neither the space nor the money for a professional buttonholer. I also trust the judgment of the operators. They do nothing else all day but create buttonholes.
How much do they charge?
