That has been my experience with Bernina's. I've been making some bags and I'm using my Bernina just because it does handle bulky seams well. Did you contact your Bernina dealer about it or just a generic sewing machine dealer? Bernina's do tend to be a bit specific and a Bernina dealer is usually your best source.
