For me.. it's the expense! Battings are so much more sturdy then they were years back that if properly tied (and close enough) the batting should not shift and be fine. I made my hubby an all flannel quilt 5 years ago. It's hand tied. I have been tossing it into the washer a few times a year (for 5 years) and it's yet to fall apart or show any batting issues. I do wash it on gentle and line dry it with just a little "dryer fluffing" in the end.
I got a Bernina 440 QE three years ago and now I have gotten into cross-hatch quilting if I'm in a hurry for a quilt that I know is going to be used a lot. I like it.
