I love my 8900. The large harp area makes sewing and quilting a dream. It is easy to use and understand. I too have not mastered the knack of the knee lift. I was thinking it was because either I'm short, the height of the chair or table I'm using or what but it just seems too far away for me to rest against the side of my leg to use it. I don't see that as a major detraction however.
