I absolutely LOVE my Juki TL2010. Bought it sight unseen based on reviews I had read and the recommendation of the guy that repairs my older machines. It's been perfect right from the box. I have never had to touch the tension. Internal parts are metal, not plastic. It's got a great amount of harp space because the arm across the top is narrower too. almost forgot, she's not picky about thread either! just about anything I've tried works great without any fiddling!
Here's a blog post about the machine. When she commented on the lighting, I recommended some lights to her for it that I found thanks to a post on one of the Craftsy classes I took.
