Have you looked at HP all-in-one printer/scanners?
The HP Photosmart Premium Fax e-All-in-One Printer (model number CQ521B) can be picked up for £99 from Amazon -
If you use the print side of it, the cartridges are pretty cheap so running costs are low, as they only contain ink, not a whole new print head unlike some.
It supports wireless and wired ethernet, so you can use it to scan to and print from multiple devices. You can even print from ipads/iphones/nokia phones/android phones.
