I bought a longarm a few years back and NOW....I LOVE IT....then was a whole different story. I didn't feel it worked properly, it had a hesistation on each start and I couldn't get it to go away. Finally had the tech come out and they set the timing and played around with it and now I love the way it quilts and it is smooth. I also think that 3 years of practice has helped. The more I practice the more I love it.!!!
Good Luck
