The 550 QE is a great machine. It has the same oscillating hook (bobbin) system that your 1130 has. If you go higher than the 550, you'll get a rotary hook system, that you might not be as happy with. However, if you don't need the BSR (Bernina Stitch Regulator) and bigger throat area, you'd probably be just as happy with the 350 Patchwork Edition, which is around $1,300. The 350 PE comes with a walking foot and Free Hand System, and a very nice selection of stitches. The 550 QE has a sturdier motor and internal shafts, but the 350 will last as long as your 1130. I have the 230 PE, which is the equivelant of the 350, and it has been my best friend for the past 9 years.
