I've had my Bernina 440QE for almost a year. My husband secretly bought this machine for me, so I had nothing to do with buying it. It came with the BSR and the walking foot and several other feet. Free classes on how to use it at the LQS he bought it at. Price tag: $3200.00. I really like the machine. I like the needle down option, the walking foot is a dream, and because I am new to this quilting thing, the throat is big enough for me....for now! The 440 has been discontinued and replaced with the 550, so I don't know what that means for me down the road. I'm not into the fancy stitches so much and the BSR is cool, but I think I like using the plain old darning foot for FMQ practice. The Bernina warranty is very good and overall, they've been around for a LONG time and they sell a great product. Hope this opinion helps in your decision.
Edited to add: I still love my old faithful Kenmore, too!
