I test drove the Juki ... it was a nice machine, had excellent lighting, a very nice frame, moved freely. Stitch quality was not bad, but not the best - this could very well be due to the fact that I am not an experienced long arm operator (I used the machine for 5 minutes to put it through it's paces). Regular stitching was OK ... micro stitching was not as nice.
I test drove a lot of machines that day and one of the things I discovered is that all of the machines "felt" different. You really DO need to test drive them, as many as possible.
In the end, while the Juki was a nice machine AND the dealer is my local LQS ... it still is not the machine I would choose. I fell in love with the Innova, and I also have a weird unexplained predjudice against Juki (I think it's all the machines I see advertised as "long arms" that are nothing more than straight stitch domestic machines with 9" (or less) harp space).
