I have 2 sergers. The first was a singer, bought back in the 80's. It sewed great but was a nightmare to thread. Had to get the book out every time to re-thread it. Then I bought a Babylock, and I love it! It automatically threads the upper and lower loopers by a jet air threading system. I wouldn't have one if it didn't have that. You will love a serger to professionally finish so many things. And I was amazed at how pretty and easy the rolled hem stitch was. Good luck on your purchase.
