I really like my MDC1300 serger. Cover stitch, elasticactor (wonderful!), blind hem, and regular foot. I haven't used the cover stitch either, but the elasticactor is truly great. Lots of crib sheets got made with this, some for my granddaughters and many more for a charity (incubator sheets). The machine is easy to adjust and pretty bullet proof except for the little needle-like item on the bed that helps with the stitch formation.
