I traded my Janome 7700 for a Juki TL2010. The Janome was too delicate for me and the issues people had w them remained in the back of my mind. It also wasn't good at going over multiple seams and was finicky/not enjoyable for piecing. Its oversized head was a bulky design and interfered w my sewing line of vision so it'd get uncomfortable from crouching. I used it primarily for FMQing.
I love my Juki! IMHO, its stitch is more beautiful than the Janome and even my vintage Berninas. It's also got a large harp, streamlined head, and is a straight stitch machine. It takes different threads and doesn't even need a leader for piecing
I can make an accurate, beautiful scant 1/4" sa easily and repeatedly so it's become my piecing machine as well! I smile every time I sew on it
FMQ on it is delightful
If you want deco stitches as well, I'd suggest looking at the brother dreamweaver. They're also w large harps, streamlined heads, and you get more bang for your buck w these than w the Janome. Similar price points get you laserpen, pivoting, and they seem to have few issues w them. I've read/heard great things about them and if I were in the mkt for a computerized, multi-stitch, expanded harp machine, this is what I'd choose.
Happy shopping ~ please keep us informed!
