I need a 10 to 15 foot KVM extender

I want to add a KVM switch to my workstation.   I want to be able to
switch between my PC, and a server that sits about 10 or 15 feet away.

I already have a 4 port  Belkin OmniView KVM switch (with USB and
audio).  I just need the cables to go to this server.

If I use 10-15 foot KVM cables, will I lose image quality on my
monitor?  Do I need special cables or a signal booster?

Please send me a link.  I am hoping to spend less then $40 for the
cables.  I also need audio and USB from this server.

thanx in advnce

You can get an extender that will go for quite a long distance over CAT5 cable.

Avocent is one company that makes KVM solutions as well as extenders. 
Here's the page to their extenders:

so which of their products would do it?
