If money is no object and you are looking for a quilting machine...I'd just go for it and get an Innova longarm!!! Oh, geez, that's what I did 4 years ago and have never had buyers remorse. I love quilting on her today as much as I did the first day!!!
For piecing I have a Janome Quilter's Edition and I love it. I have a Bernina Artista I use for embroidery, but I find that the Janome is more user-friendly. That said, I would never want to quilt on either of them!
