I have sewn for about 45 years. I had a cheap serger for awhile and hated it and finally a couple of years ago I did research for what I was looking for in a serger. One thing I knew I wanted was a built in needle threader and something that was easy to thread. I bought a Juki 734 DE and LOVE it. I think it cost me about 900. and was worth every penny. I had to buy online because I do not have any place local that sells machines. Once I knew what I wanted, I just checked around for price and quality of the place I was dealing with. Here is a link to my machine on
amazon.
