Quilter1 and I have a lot in common!! I, too, have the 830 Record and recently DH gave me the 750QE with the BSR... I haven't used it much yet, but I can tell I'm going to just LOVE it!!! what a difference it makes...
I imagine that in most cases you'll get excellent service with a Bernina... for many years... At least in OKC, they treat you like you are very special!!
