I also have a BabyLock Evolution. I upgraded from a Babylock Imagine that I had bought used many years ago. I LOVE this machine. I also am an avid sewer in addition to quilting, so I use it all time when sewing clothing, drapes, purses, etc. I have never used it for piecing. Seems to me it would be overkill in the thread use. Prior to my used Imagine I had a Riccar and it was so frustrating and so hard to thread. In my humble opinion, if one is going to buy a serger, go Babylock with the air threading. I know they are more expensive but buying a used one beats a brand new one of another brand.
