Sew sew

I really really need want a new sewing machine. I can't really spend more than $200. I am looking for something that is simple to operate and adjust. I know how to sew and can do complicated things, but don't really do anything more complicated than simple garments and hemming and a little bit of quilt piecing. I want it to sew well and smooth (which probably just about any new machine will) and not need a lot of attention. Something that will last me for quite a few years... currently I have a hand-me-down Brother that's okay, but I have never learned really how to adjust it right... I am thinking of switching to a Singer, but really have no clue how to tell what is good or not. Any help is appreciated!
