Nothing like answering my own questions. I posted this over a year ago, and since then I have actually purchased the Crescendo. I'm very happy with the machine. First off, be sure that you do some comparison shopping regarding price, if you have some competitive dealers in your area. One of the problems with these high end dealers is that they have exclusive territory, so it's difficult to deal. I was lucky. The first dealer I went to for a demonstration was really awful. They made a good price offer, but I was able to locate a much friendlier and cooperative dealer who agreed to match the price. This dealer was also very responsive when ever I had any questions that needed answering after the purchase. (For anyone in the Western New York area, the dealer I worked with was Sandy Pirdy at Creekside Quilting in Arcade, New York.)
Second, be sure to go in for a demonstration. There are a ton of features on the machine, and you want to be sure that you will use all or most of them. No sense spending all that money for features you'll never use. My machine does NOT have the embroidery features on it, which was just fine with me. I'm a long time sewer and knew that machine embroidery didn't interest me. There are lots of regular sewing stitches and decorative stitches on the machine which I use. I did, however, purchase the free motion quilting kit, which I found very helpful in improving my quilting and keeping my stitches uniform. Like all free motion quilting, it still takes some practice with this equipment.
The things I like best about the machine: Lighting is wonderful! The older I get, the more I realize that I need more light to comfortably see what I'm doing and to continue to sew for long periods of time without getting fatigued. The bed of the machine is nice and big. It really does make a difference. I'm absolutely crazy about the automatic thread cutter!!! Over the course of a project, it saves lots of time and thread mess. It's also nice that it cuts the thread just the right length, so that you never get any of those nasty thread nests when you start the next seam! The automatic needle threader is absolutely super. It is really and truly automatic -- the machine practically threads itself. The Crescendo, is also very substantial -- read heavy. For me this is a plus because it's very stable, and I have no plans to tote it around to classes. Of course, everything on the machine is electronic, and it is very easy to use. In addition, it comes with a great user's manual, which is very well written with good illustrations. Of course, as with most higher end machines, the stitch quality is just wonderful. I'm especially impressed with the buttonhole set up and stitch quality on buttonholes. When ever I buy a new machine, I always look at how easy they make sewing the buttonholes and what the stitches look like. Nothing like spending hours on a project and having it look shabby because the buttonholes are a mess.
Hope this is helpful. If you have specific questions, please feel free to email me.
