I’m in the process of starting an alteration business, and my next purchase is going to be a serger. I’m trying to decide between Singer, Bernina, and Baby Lock brands, and of course am wondering if I should buy new or used. I hope to keep my purchase price down, but still want a good, reliable machine without alot of bells and whistles. So I thought I’d ask you all what you think. Thanks in advance for your thoughts!
