You can get a Bernina 330 for $850 to $900. Solid machine, but not a lot of bells and whistles. The Bernina 350 is around $1300, but comes with a walking foot, free-hand system, more stitches and a couple extra quilting feet. If you could find an older used Bernina they're great, but may not have the blanket stitch for applique.
Good Luck with your search!
