The Kenomre you show and the Janome DC 2010 are virtually the same machine and share the same manufacturer. I have the DC 2010's in my classroom. Never had a problem so I don't think you could go wrong with the Kenmore.
I own all 3 - Brother, Kenmore and Janome. Have always had good luck with them. The CS6000i's, I've heard, are either great or have problems, guess it's just the luck of the draw.
