Here's my 2 cents......I bought a 440QEE in October 07, well I tried it, loved the emrboidery part but absolutely HATE the BSR and determined that I am no good with free motion quilting.
So that being said, I went back to my local dealer where i purchased my 440 and they allowed me to trade it in with full purchase value and I purchased a 630E. I am much happier and even though I send my quilts out for quilting I still love my Bernina.
You really do need to test it out and make sure you really are going to use the features it comes with and get the best machine for your needs.
I know I'm happy now with my new machine.
