I have to say that I am very happy my with HP Officejet Pro X576dw. It has a flatbed scanner-copier, color and black and white, with multiple options of all kinds, as well as an autofeed. It is better than the large industrial size one I used in my last office share. I think I paid around $500 for it last September, but is now going for around $300 I think. It is really fast, quiet and problem-free.
From my own experience, in these days it is essential to keep your documents electronically by scanning them all. It makes work so much easier and portable, especially if you start hiring staff.
