I have 2 Juki TL98E machines, they have all metal parts and a darning/FMQ foot, Walking foot,Straight stitch foot and a compensating foot, which makes a perfect 1/4" seam. They are work horses and work as long and as much as I want to work. They should be oiled every 6 - 8 hours of sewing and I clean & oil the bobbin area everytime I put in a new bobbin. Bobbins hold more thread than any other machine I have. - 3 others. I am happy with the Juki. I make twin up to queen and maybe a bit larger. I quilt on my dining table.
