Hi, I have a Janome 8077, my first Janome, I had 6 Singers which I had always been happy with until the last two. For some reason they didn't last very long.
The Janome I have had for nearly two years, I think. When you get my age times flies so fast that you sometimes miss a year or two. But so far I like my Janome. I have been making quilts on it and it hums right along. I did take it into the machine shop about 6 months ago but I think it was a ID 10 T fault. It has only 30 built in stitches and that includes button hole and I haven't tried that. I don't think my quilts need a button hole.
Sorry I can't help you more. I guess you pays your money and takes your chances.
