I had a Singer serger for years and used it rarely because it was hard to thread and set tension. I finally bought a Baby Lock Evolution. It is wonderful! Self threading and auto tension. I use it all the time. Any of the Baby Lock sergers would be great. People who have the Imagine rave about it too. They are a little pricey, but worth it in my opinion. You can find them on eBay sometimes. Baby Lock has a new serger just coming out. You might be able to find a good used one when people trade up for the new model.
