Trying to set up a cache proxy server for my local home network

Hi
I have 3 computers at home and I want to set up a proxy server to help with bandwidth etc. My computer is connected to the cable internet. At present I have internet sharing on but would like to run squid to reduce the amount we download.

I would like to use squid as this seems like the way to go.

Unfortunately I can't see to find a valid link to the latest version of squid for Windows XP. I downloaded version 2.3 but didnt have succuessful running it. I kept getting
an error 1067 (or so) when trying to start the service from the "service" control panel in windows XP.

So the points are for basically helping me get running squid on my computer version 2.5 or 2.3!! P.s anyone know a link to version 2.5 that works and how to get it up and running?

Thanks.
