Hi gailjo and welcome from me too.
There are a few of us who have coverstitch machines and there are already a few discussions on them your will find in the
Overlockers and Coverstitchers section under
Machine Talk.
I love mine and use the chainstitch for sewing up toiles almost as much as anything else. It's great because it's much more secure than simple basting but it pulls out even faster.
I only got my first overlocker in 2014 and can tell you that I've found using the coverstitch, bought 2 years later, much more intuitive than I did the overlocker at first.
