I don't believe a serger is a machine you would use enough to
compensate for the price. I have read you really need a 'good'
serger. Cheap ones you will have a lot of probelms getting the tension right. You have to buy a lot of thread to sew on one.
I would put the money into buying a better machine for quilting/embroidery.(?)
I have been quilting for 40 years and have never thought I needed a serger.
