I just bought a Bernina 770 because I fell in love with it and I don't have many other addictions in my life
I've had a Bernina computerized (150QE) since 2001 and it runs like the day I bought it and has never had a trip to the repair shop.
I also have FW's, and a couple of other old Singers that I love and use occasionally, knowing that I will always have a backup if I need it.
I've never been fond of cheaper machines because of the disposability factor. I'd rather have an old Singer any day that something not made to last. I'm like that about a lot of things.
I do see your point but I guess I don't really agree with it. I love the bells and whistles. For me they making sewing more enjoyable.
