I love my Bernina 440 QE. I don't know about similar models that are cheaper because I have little experience with comparing models and manufacturers. My husband "gave me this Bernina for Christmas" -- tee hee -- but I waited until the following September to actually purchase it when a local store had its annual 25% off everything-Bernina sale. Since I bought this machine, I have discovered lots of people who own this model and I've never heard any complaints about it.
Incidentally, I did not get the embroidery attachment, which was an additional $1,000, because I am not interested in that whole 'nother aspect of sewing.
