I have a 2-port linksys switch With cables, from micro-center it was 69.99, 
only catch is, the keyboard freezes when switching from one box to the other, 
at least between win and linux.  I think the problem is fixable but it will 
require me to figure out what differences exist between the win and lin 
implementation of the keyboard.  Not easy, and probably time consuming.  
Before anyone buys a switch, I would recommend searching about to see if 
other users have problems.  The linksys switch has virtually no image 
degradation at 1152x820 at 75hz, but if you have a big huge fancy monitor, 
then you will probably have to spend some real money to get a good picture.
