I love, love, love my 6600. It does everything I ask it to do, and I make a lot of quilts and bags. The walking foot is amazing, but even without it, the feed is so even when piecing, I rarely pin anymore. I doubt this is a purchase she will regret. I'd buy mine again if necessary, and hate to think of purchasing anything else for my girls when they need a machine of their own. (They are spoiled and call dibs on the 6600 when they are both sewing a project at the same time. )
