Look through some older threads on this board as there is LOTS of info/advice on machines. When I asked the same question, some of the best recommended going to a quilting show and 'test driving' lots of machines from vendors to figure out what I liked. Or you can do the same at your local sewing machine and quilt shop stores. I ultimately decided on a Juki TL 2010Q as I wanted a straight stitch work-horse machine with the largest harp I could afford and I love it. I also really need the speed regulator for consistent sewing, and love the automatic thread cutting feature and the 'hands free' knee level to raise/lower the pressure foot. It is a big investment so just do some shopping around and take your time until you find what you like based upon your budget.
