I adore my 440 QE - I saved up for 3 years to buy it. I agree with all the advice above, buying extra bobbins (not the cheap knock off ones you'll regret it), watching the DVD and taking classes. I love the BSR but I'm also learning FMQ without it - I suppose the concept of how FMQ was helped along with the BSR.
I did not buy the embroidery option.
