Juki is also coming out with a sit down long arm sometime in 2014. I was told in the spring hopefully.
I really liked the Juki longarm. I'm a sit down quilter with a Tin Lizzie but had the Juki been out I think I would have gotten that instead. For the money, I just like the Juki a lot.
I have a friend who is planning to get the Juki sit down hopefully this spring if they're available at Paducah this year. We'll see
In my guild we have 4 big machine quilters... me with my sit down (I used to have a Bailey 15" on a frame. They didn't offer a table option when I wanted to switch to sitting down), one lady has a big HQ with all the electronics. She quilts for others for a living but only does pantographs, one lady has an Innova and loves it and the last has a 15" Bailey and she likes it as well.
I suggest going to a big quilt show and trying out as many machines as you can back to back. Narrow it down to the two you like and then quilt for a bit on one then go directly to the other one and quilt on that one so that you can really compare them side by side as best as you can.
It's a big decision with a big price tag. You really want to do what is best for you. Everyone has a favorite. Mine's my Lizzie for now
