Voila! It was a complete surprise, too. He picked out this particular model based on reviews online, and so far so good.
He also rather wisely gave me some reading material to go along with it! After perusing the book, the serger manual and other blogs, it seemed like threading the machine would likely be my biggest challenge. I was prepared! It must have been beginner's luck but I managed fairly easily. I tied on the new thread to the spool the machine came threaded with and just pulled it through. It worked for one out of three spools. For the rest, I just followed the manual. I've already started a project from the book and will write more about it soon.
