I have an old White serger (bought in 1985) that I don't use anymore because I wanted a 4 thread. But it serges beautifully Then I bought a Bernina serger - sews beautifully but it fought with me every time I tried to thread the loopers. then I fell in love with the BabyLock Imagine - it automatically threads the loopers with a push of a button. Sews beautifully, came with 6 extra feet, automatically adjusts the tension. It's my favorite.
