That's good to know, annesthreads. I will be trying out several machines this Saturday when I make my trip to the sewing machine dealer. I love the harp space of the 7700, but also love the strength of the Juki F600. I do plan to have more than one machine down the line, so perhaps I can always add another high power machine for the bag making purposes. I plan to do a lot of quilting and the 11" harp space on the 7700 sounds quite enticing, as I would rather try to do my own quilting instead of bringing it to a long armer.
Have you had any issues going over bulky seams when it came to quilting with the 7700?
