I have the 6500 and LOVE IT! It does everything I need it to. I do my own FMQ on it too even though I'm still learning how to do that! I don't really have any dislikes about the machine. I bought mine online with a 30 money back guarantee if I didn't like it. I have had it about two years now and use it every week. To me it is a great machine. Just a bit above the basic machine with all the bells and whistles I need.
