On another note, I test "drove" the Bernina 550QE. To push its limits and see what it could do, I sewed a french seamed, double turned hem piece of canvas on it. I was shocked and impressed to see it sail right over that seam!! The stitches got a wee bit smaller, but not really noticeably. I think I found my one machine that can do it all (for me). But I am in sticker shock and don't know if I'll ever recover!
If I ever do recover, I might just buy it and sell the Viking. I think I'm getting too attached to the 201 to sell it though...we'll see.
Thank you all for sharing and helping. I'll update after the Viking gets serviced, and of course if I end up buying the "Nina."
