I bought my Pfaff Creative 1471 last year from E-Bay and it came with a warranty and was reconditioned when I bought it. Have had NO problems with it.
I am a new quilter and besides that never learned to sew. THe Pfaff was very easy to learn to use. I looked for four things in a machine for quilting after doing much research. 1. the ability to drop the feed dogs for free motion quilting, 2. can sew thick or heavy fabrics easily 3. the needle down feature. 4. an even feed or walking foot.
The 1471 comes with 99 built in stitches which I have used in machine quilting. You can also program your own. I took it to a quilting class and the teacher looked over, saw it and said: Good choice, that one's a work horse.
hope this helps :)
