I would recommend Nolting machines. They make all sizes, from the Fun Quilter (various sizes) to professional models with a 30" throat. Definitely make sure you have plenty of room....the table size will determine the size of quilts you can load, and Nolting can make really any size you need. Can't say enough good about their customer service. Was just at there shop today, in fact, and traded up to a 24" Pro model. Love the staff there...extremely helpful and knowledgeable.
