I love my Brother 1034D serger - I use it all the time and it just keeps on tickin'. (I think it's made by the same factories that make the Babylock) Mine's about 3 years old, now.
It's the easiest thing in the world to thread - and only 2-3 seconds to switch back and forth between rolled hems and regular overlock stitching.
