Check out Janome HD3000. It is an electronic model with everything a quilter needs but not a lot of extra fancy stitches. It is "heavy duty" with 1 amp motor and very quiet. The Brother PR420 is loads of bang for the buck--computerized with more stitches. You also might be able to get a Pfaff Select model (mechanicals) in your price range.Those have the advantage of built-in dual feed. I personally feel those are your best options in new at $500 or less.
