I looked at and priced out all in ones as part of my research for getting a used one. The unit I was offered was a Canon Multi Function, scans in color, but only prints in black and white. The company that was selling it offered it to me for just slightly more than I could buy a refurbished one (which would also come with a warrenty). The wanted to sell it to me for $200. It is barely used, but I can and have found cheaper.
So, I'm passing on this unit for the time being. I'll save some pennies and I've bookmarked a couple on line sites that sell them and in a few weeks, I'll make my purchase. Prices range from $145 to $393 new. I had hoped to spend part of the weekend scanning the piles of paper in my filing cabinet and on my desk, but tis not to be at the moment.
