Straight stitch
Hands down, Janome HD9. I did alot of research on this machine before i purchased it. There are alot of comparisons and reviews about this machine versus the JUKI.
JUKI are good machines, however the Janome HD9 came out ahead on the features. This is a heavy duty machine that can sew thru 8 layers of vinyl And even more layers of denim.
I use it in making bags. Quilt piecing and free motion. The Bobbins hold almost 1.5 times more thread. The throat space is 9 inches to the right of the needle, and 6 inches high throat space.
it sews 1600 stitches per minute and has variable speed, auto thread cutter and many other features.
