Microsoft wireless laser deskptop with the 6000 keyboard & 5000 mouse £32.77!!! (if you qualify for free delivery like many of the people on here or wish to collect it (from Bolton))
I treated myself to one of these last week as been after a laser wireless desktop for ages. This is the cheapest one I could find at this quality from either Microsoft or Logitech.
Very happy with both the keyboard and mouse so far and look stylish too.
Plus required very little in the way of installation (the keyboard wireless frequency needed re-scanning once) and that was it!
From scan's website: "The sleek, ultra-thin Comfort Curve keyboard of the Microsoft Wireless Laser Desktop 6000 encourages natural hand and wrist positioning for unprecedented comfort and productivity. The included high-definition laser mouse adds greater performance, precision, and accuracy."
