[comp.sys.ibm.pc] LOOOONNNG video and keyboard cables

I saw an ad in a magazine (PC Magazine, I believe) for a device that will
hook up to your video out port and keyboard out port and boost the signals
along anywhere from 25'-250' to your keyboard and monitor.  I've been
wanting something like this for a long time.  However, the ad puts the
prices (depends on length you want) from $100-$300, which seems
ridiculously high to me.  I'm not much of an electrical engineer (which is
why I never made one myself), but it seems to me that it's a fairly
simple device.  Does anyone out there know how to build one?
