I was talking to a gentleman who quilts at a garage sale last September, he had this machine and absolutely loved it. After he'd had it for a year, he bought one for his daughter for Christmas. I recommended it to the mother of one of my student's who wanted to get her daughter a machine for Christmas and so far no complaints! So I think it's a good deal.
There is also an upgrade to this machine. It has a few more stitches but other than that, the only difference I could see between it and the 6000 was the warranty and the price. It's the XR9000. I think Amazon has the best prices on these machines.
