I have a 440 QE and it is very good. However, I don't like the front load bobbin. I have the BSR, and find that I FMQ better without it. I would suggest to you that you look at a Baby Lock or a Brother. I have a Project Runway Brother to take to class and love it.
Just my opinion. If I had to do it over again, I would go for a good Baby lock and spend the extra money on something else.
