If you're looking for a wireless laser desktop combination mouse and keyboard then i can tell you from my experience getting the Microsoft Wireless Laser Desktop 6000 is a very good choice i can highly recommend it. The mouse is brilliantly designed to give you allot of comfort and it has 2000dpi giving great performance and accuracy. The keyboard its self is very comfortable having a soft pad for you to rest on while you type. Now allot of people might be put off buying a wireless keyboard and mouse because of lag during gaming but i can tell you that this product does not have any lag wot so ever when playing games. It is also very cheap for what you get in terms of good quality build and performance, its around £30 i got it from Scan.co.uk.
