I have the Innovis 4000D, which is the next step down, and I love it. I paid $5000 for mine, it was a demo machine at the country fair so I got a deal, included all the software and classes. It's a lot of money for sure but I've never regretted it.
The only downside is it is a combo sewing/embroidery machine and quite frankly I will never use it for sewing although it has outstanding features and would be great for quilting. The reason I don't use it for sewing is I have it embroidering constantly. I have a back up machine for embroidering - a Bernina Deco 650 - but it can't do what the Innovis does. I've thought about quilting on it but I have it up high on a dresser for easier accessibility and would have to move it and set it up on a table and it's just too darn heavy to be moving around.
