I have the Sapphire 870 and although it was a learning curve when I first got it, I am very happy with it. It does NOT do embroidery though, so not sure about a previous comment by reneaunoel. I usually use my spring foot when doing FMQ... (and make sure to change the settings on the machine to match) I am not that great at it, but I'm pretty sure that is operator error.....I know what I should do...but I don't make the time to practice enough. The books that came with the machine are pretty good...and every once in awhile I refresh my memory and am amazed at how much I have forgotten.
