I love my Janome 8900QCP. I bought it for three main reasons: the large harp (11"), it's ability to got through a 1/4" thick piece of leather, and cost.
I like to make large quilts and it is easier to fit the quilt through the larger opening when piecing. I may even try to quilt some smaller projects on it. I have a Innova for quilting, but it would be fun to try to finish a smaller piece I have from an earlier Trapunto class on my Janome, now that I have a larger harp.
