So very glad for you! I bought my 6600 in 2008 and it has been a wonderful machine. In 2014 I wanted to upgrade my embroidery machine and bought the 15000. Kept the 6600 and use it regularly to this day. The only service the 6600 has ever had was cleaning and checking once every year or so. I had to replace the bobbin holder once upon a time, but that has been the extent of any repair type work done on this fantastic machine.
