I have both the Janome 720 and 760, they are pretty basic, the 760 has more stitches. In my classroom I have Janome DC2010's and Ken's Sewing has a used one coming in that he's selling for $299 (new they run between $400-500), the shipping is free. You might look at that, it's a really good machine. It doesn't have the knee lifter (also available in other brands, not just Bernina), but it has everything else you want.
