Best way to transparent proxy?

I'm in the position of redesigning our network and have read some very
good things about transparent proxying and squid (and am currently using
squid as a normal proxy).

I'm also getting a new circuit and so am buying a new router.

My Question is: Having read the Squid Transparent Proxying FAQ - What is the
*best* and/or fastest way to provide transparent proxying. What hardware is
required? Cisco router, Linux box with single NIC? or Dual-NIC Linux
box configured as a router and just not use the backbone router at all?

Any advice is appreciated.
