Copying manuals to sell is another one of those hot buttons, obviously. I'm all for looking for a free one if it's available somewhere, but sometimes it's not. Two trains of thought here-
1. There are people who go about it legitimately. Linda Wilkens spends tons of money in legal fees to own the rights to the manuals she sells and she reproduces them in very nice hard copies as well as PDFs.
2. To my way of thinking the manual is one of the most important tools to have for a machine, any kind of machine not just a sewing machine. Especially if it's a machine you're not familiar with. I don't understand why someone wouldn't be willing to pay for a manual to be able to operate and get the most out of a machine, regardless of how much or how little the machine costs. I bought one of my embroidery machines used and if the manual hadn't been with it I would have gladly paid for one if I couldn't find a free one.
