And if you go to Ken's Sewing Center as 'Kat sews' suggested, web site: www.kenssewingcenter.com/ they will work with you and will give you a good deal on whatever machine you buy. I have the Brother 1034D that I purchased form them. This is my second one, I dropped the first one and broke it, and bought my second one from them as well. This has proven to be a simple, easy to learn, very user friendly serger. Go on line and do a comparison of the low end sergers.
For years my fellow (local) sewers kept telling me that once I bought one I would wonder how I got along for so long without one. That is so true. I was of the old school mindset: Cut the edges as straight and narrow as possible and zig-zag them. Well I wonder, how did I sew so long without one. And Good luck.
