I don't want to make this a bad review. I originally owned a 1034D serger for about 8 years and it was a work horse. I loved that machine. It finally broke down. I purchased this new 1034D and I never could get it to work correctly. I had to take it over 2 hours away to have it worked on. It cost me 1/2 of what I paid for it to have it repaired. The timing was off on it. I have started working on a craft project that requires me to serge through many layers and over a zipper end and this model machine can't handle that. 
                    If you just need basic surging this model is great. I've used my original machine to sew 100s costumes for a repertory theatre I'm the costumer for. So yes this is a very good machine. I just got a slight lemon this time and don't think it can handle what I'm doing now.
