I had a D1 for a couple of years and loved it, but the quilt shop I worked for offered us an upgrade deal to the SE when it came out, so I upgraded and love my SE as well.....a dear friend found out I was trading in my D1 and bought it from the quilt shop before it ever got cool...she still uses it all the time in her quilting and monogramming business. HV machines are excellent machines, my only problem is that our nearest dealer now is about 100 miles away, so when it's time for service, I have to plan a trip to take her in and then another trip to go pick her up .
