I purchased the HZL-DX7 in April. I believe it is basically the same machine as the DX-2000QVP, minus some presser feet. I'm in Canada, and was told that the DX-2000QVP wouldn't be available here. Anyway, the DX7 is a great machine. I've used it for piecing, FMQ quilting, applying binding, doing decorative stitches on crazy quilt blocks, etc.
I don't do garment sewing any more, but the machine has all the features you would need for that. It comes with many presser feet. It's very quiet. I've used different types of thread with no problems whatsoever.
I would have liked a larger harp ... but I have the TL2010Q for quilting larger projects.
I would strongly suggest that you look up information on this machine. It might be what you're looking for.
Keep us posted.
