I work at a place that carries Bernina and HandiQuilter. We have opted to NOT get the Bernina quilting machine. After all the problems with the $10,000 Bernina 830 embroidery machines, there is no way we want anything to do with their over-priced, first out quilting machine. Not every Bernina dealer can sell or repair these machines. They have to get a separate dealer license and training to do so.
Have you seen the new Handi Quilter Infinity? Now that is an awesome machine!!! Here's a link...
http://www.handiquilter.com/hq_infinity/ It goes 3100 stitches per minute, so there is no way you can out run it. It has the hand wheel control on the screen. It also has the tension control on the screen, and there are pre-sets for different threads. They put a new lighting system on it, called the Light Ring, that puts a ring of led lights just above the needle area. You've also got UV and black lighting, so you can see difficult to see threads. There's even a camera underneath, so you can check the stitch quality on the back, as you quilt. Our HQ rep just came to train us and said their engineers have been working on the Infinity for about 2 years before they announced it in November. You can bet they have the bugs worked out of it before it went to the dealers. Don't think I can say that about the Bernina quilting machine.
