I have owned this machine for over 3 years and quilt on it 95% of the time. I take it to retreats or sew-in too. The only problem that I have had is the bobbin winder feature, but I use a bobbin buddy unit so I don't have to worry with it. It sews great and it will sew thru 4 to six layers fairly good. I use my quarter foot on the machine and have to change to Option "01" each time I start, or I break a needle hitting the quarter foot. I bought my unit at Walmart for under $150 with all the attachments, extension bed and cover for machine.
