I went to my local store tonight to compare the QE 4.2 and the Performance 5.0. I really liked the Performance 5.0 better. I thought the interactive display was more intuitive. I also like the quilting maxi stitches. I can see actually using those frequently on smaller projects like placemats. I'm still not sure it's worth the price difference, but I know me, and if I settle for the lower machine I'll never be happy since there are things on the Performance I would really like to have. Now the trick is going to be waiting until there is a special on the Performance and a financing deal available. As much as I want it, I do not want to pay full price.
