Here I found a website where you can get the keyboard/mouse combo that The Amish Kid suggested -
Although you said 30 pounds...so this may be out of your reach?
I have the MX3100 which is the same as the MX3000 but mine has the better mouse (MX1000 rather than the MX600) but the keyboard is the same. So all I can say is..the keyboard rocks...it's got really good range...sometimes I get it in the next room (and I have double bricks in my house lol). But yep, the keyboard is good, got a nice touch, nice buttons just overall quality.
Other keyboard/mouse combo's i've owned haven't been that great so I can't really recommend any..
