I've had mine for 5 years with no problems and use it solely for quilts plus I sew on the bindings by machine. I have only made 6 quilts, but I quilt them myself - sizes from king to twin - and no issues at all. It's a fun machine with plenty of harp space and lighting. I've used quite a few of the specialty stitches. The 7700 yahoo group has just about died out, but hopefully you can search the discussions.
