Why is it so hard to find info on throat/harp space? If/when I upgrade to a new sewing machine, I would definitely want a larger space than I have on my current machine. But it seems so hard to find that info on most sites. I was interested in getting a used Bernina Artista, but I can't find anything that tells you what the harp space is. Really frustrating. Would be wonderful to find a site that has a chart of all the sewing machines to compare.
