My Juki 2010 is the strongest, but it is straight stitch only. My Juki 85 is strong but the bobbin rattles and I don't like some in the stitches. My old Pfaff was my favorite best all around, heavy duty, great stitches. My Esante embroidery , has the clean stitches but feels cheap even tho it isn't. I bought a cheap Singer for 20.00 at a yard sale for the kids. After cleaning it I really didn't want to give it up, but I had already promised the kids. I paid 400 for my kenmore years ago, well worth the money, it's a workhorse.
