Hey Everyone,
Thank you so much for your help with my question.
I bought the Brother DZ1234 and so far I am super happy with it.
Now I have to find a way to get rid of my Pfaff Coverlock 4872 and all my accessories and I will be in great shape.
The DZ1234 has a much smaller footprint, and it does a great 4 thread overlock, which is all that I will be using it for.
Thanks again for all your help.
Julie
