I have the Bernina 440 also, I bought this machine probably 5 years ago when BSR first came out - just had to have it. I love this machine and could never part with it. the BSR is good, it is not a foolproof method for great FMQ though, you still need to practice practice practice. I'll FMW smaller items, but for my larger items I still rely on my favorite long arm person.
Good luck in your search!
