I have bothsewing machine and serger and honestly for me I do not need both for the type of sewing I do. Maybe it is just my serger (I don't have a dream Babylock) but my sewing machine does a great job and I do have the time to finish them seam as I would wish with it, and a bit more control. Saying all that I would suggest look for a good machine to suit your sewing needs, see how much time you have to allow to sewing, because there is no doubt a serger is fast, however take time to thread on some models. But if you are like me I had to get a serger to know how much I needed one

I have a Janome 6500Pro, I love the thread holder!, I love ability to control the speed!, and the number of stitches. I am not a quilter as such, so I find the 6500Pro does the job for me. Hope that helps! Let me know how it goes.
