I have had a serger for 20 plus years and used it for all sorts of other things, but never wanted to use it for a quilt. Think of all the thread you will use. And if your seams are not accurate, tearing them out is awful. I sould stick with a good sewing machine that does a good, solid, locked stitch with a 1/4 in foot. That is about all you meed in sewing equipment.
Other will have different opinions, but this is mine and it is free.
