This is what I suggest, first find a local shop that will do repairs and upkeeps (like oiling). Then ask yourself how much you can afford to spend. Then what do you really need your machine to do like: my favorite- automatic thread cutter (this is great when quilting on your machine), decorative stitches (especially the button hole for that effect to outline appliques), make sure it has a walking foot, and anything else you feel you want.
