Definately try it out. I have the 875 and really like it but the first one had to be replaced, the feet wouldn't stay down when I was doing free motion, they tried everything and couldn't fix it at the store so i got a new one!! that being said, I love the cutting, treader, all the stitches even though I only use a few, the speed control button and on and on. I would recommend that any machine you purchase that they can service it there for you.
good luck
