I love my elna Quilter's Dream.

Babylock Espire hands down, I love it, can't say anything bad about it at the moment

My thoughts: Janome Horizon, Pfaff SmarterC1100 Pro, new Babylock Serenade or (outgoing model) Quest Plus, Janome 6600/Elna Quilting Queen 7300. All of those have built-in dual feed (IDT). I have the Quest Plus and LOVE LOVE LOVE it, especially the IDT. It was easy to learn, the stitches are superb, and it comes with the feet and accessories quilters typically want like a large extension table, 1/4" foot, and straight stitch plate. I would expect the new Serenade to be even better. I only didn't buy the Horizon b/c it was much more expensive, and I wasn't sure that I'd get back to quilting enough to merit the expense. I also have and LOVE a used Bernina 440 with BSR (which I haven't used much yet). I'd have a HARD time choosing between the 440 and the Quest Plus. I like having both!

One thing you can do to help you decide is to join the yahoo groups related to the machines that interest you. I've learned so much from the Horizon group and groups for modern and older Berninas.
