Sup quake playing peoples. I need your help.

I play quake left handed so I use the numpad as my primary quake bindings (with my right hand)... I have also recently moved to a new place but the size of my room is smaller, this means my desk is smaller so I cant use my mouse pad to its fullest extent (normally fairly low sens player).

Current desk is around this size link, maybe a little larger.. As you can see for a low sesitivity style aim its crippling.

However I could gain more space by buying a separate numpab and only having that and my mouse on the desk when I play. yippiii

I was wondering if any of you guys and girls would know a good product to buy. I would also appreciate having very silent keys as playing quake on a loud keyboard/numpad is " loud ".

Budget is not an issue just as long as it not ridiculous . Say a maximum of £100.

I would also be open to recommendations for keyboards although that doesnt really solve my space issues... Having a numpad is a must.
