I have a Bernina 800DL Serger. I love it and $350 is an excellent price as long as the machine does not have any issues. It does not have auto threading but the threading is not that big of a problem. Much easier than the first serger I had. I'd recommend you to test drive it if possible. Sorry I didn't get back to you sooner. Been camping for 2 weeks and were without internet until tonight.
