I have a Brother SQ9000. When I turn it on there is a display on the right that lets me pick stitch type, length, and the seam allowance. I love it. This machine was only $199.00 before tax. There are some that will even tell you when the bobbin is running low.
As far as finding an older machine, I am sure they can be found. If you research them, you may find something you like.
