I bought my Janome 350E from a dealer about an hour away, but since have found a dealer in the city where I live who will service my machine, and even do one on one teaching for any software I'm having a hard time learning. I can't imagine any dealer refusing to service a machine or helping learn the software --it all only brings in more business.
As for a machine to do quilting -- I rent time on a computerized long arm and love doing my own quilts that way.
