I have a viking 18x8 on an imperial frame that I quilt on, a Viking mega quilter that I piece on, and a Viking Diamond that I do embroidery work on. These are the machines that I use the most. I have several smaller lighter machines that can be hauled around when needed. In all I have 22 machines, some I use and some I just collect. As long as your machine does what you need then that is really enough. For me sewing machines are kind of like quilts I just never have enough or get tired of them!!!!
