I have the evolution and love it. I thought I didn't need a coverstitch machine as it has it but it interrupted my flow and ended up getting a standalone one too. I do use the decorative stitches on it. If you won't then get the imagine or enlighten with standalone coverstitch. BL lost their jet air patent so juki is making them now but you have to do the tension (BL is automatic) - something to consider. Juki is a great serger and might be less expensive.
