I have a Baby Lock Imagine serger with Jet Air threading. I LOVE, LOVE, LOVE it!!! I had a Pfaff and when it had to be re-threaded, it would take me all evening, and I would nearly lose my mind! I paid $1500 for it, and sold it on Craig's List several years later for $25 just to get rid of it. I probably could have gotten more, but just wanted it gone. I hope the lady that bought it had better luck than I did. I would highly recommend a Baby Lock serger.
