I have an Evolve and didn’t find changing over too bad but frustrating when I really wanted to do a small bit of coverstitch before I had finished all the overlocking.
I succumbed to an Imagine OL when I spotted one at a really good price and kept the Evolve as a coverstitch .
The I succumbed to Efemera’s BLCS as I wanted to use the knit binders I had which I couldn’t fit on the Evolve.
So now the Evolve is boxed up and in storage as a backup for either (and I’m broke, but I don’t care
)
