getting started with Squid - suggestions on a router?

[Kevin Dankwardt <k@xxxxxxxxxxxxxx>]

I am trying to get started in a pilot project with Squid. I want to buy 
an inexpensive router to use as well. Apparently I need a router that 
will run WCCP and that means a Cisco router.

So, can anyone give me any leads on a cheap router that will work? Used 
would be fine.

thanks.
