I have had the cs6000i for several years and take it to several retreats each year. Several ladies have purchased this machine after having seen how mine just hums along. I have never taken it for maintenance and it is so easy to take apart and clean. I thought maybe it was going to start giving me problems so I looked at the next one up from this but didn't purchase. Found out I was using a wrong bobbin in it. lol I also have a Janomi mechanical and a bigger Brother I purchased because of how well the cs6000i worked but I hardly use it. I just like the little one so much.
