Mine are both Pfaff. I too am looking for another serger as the first one is getting to old, but that's the baby I go to mostly. One day it will stop. The new is a Cover Style and still learning. So far the last two days, though, plain serging is working well, but changing to the cover stitch can be a bit challenging. I was not impressed with the Brother limited edition or the thread carrier on it. So that means one hour drives to other stores that sell different models to check them out. I serge lots, and would like to have that extra easy one again. But as you say, newer models change. Sorry I can't be of much help.
