I bought a Juki TL-2010Q about 2-3 months ago. LOVE IT! It is a high speed straight stitch machine. I did not want/need any other stitches. I use it for piecing and quilting.
Like someone else said, figure out what you need/what/and will use and research those machines. Alot of my research was done on this board. I knew I did not want a computerized machine ( I am more of a mechanical girl). The Juki is very easy to learn to use and is so fast...it is like the Indy car of sewing machines.
