I have 3 and one that is my mom's old machine - each sews well, and I use them as needed; my good machine is also an embroidery machine, but I use it for my quilting also - and my regular machine I use for mending and tough projects. It is handy to have a backup. I have a serger and have not really learned to use it yet; we got it at an auction and I have not taken the time to learn how to rethread it - and although I did use it for a short duration and loved it - I have not gotten back to it.
