Network Topology Diagram

[AdmnPower]

I'm looking to make a network topology diagram at work, I already have it sketched out on paper so I'm trying to find a good application that I can use to make a digital version. Something a little better and more professional than ms paint. I've got a version of cisco's packet tracer that I'm thinking about using but I figured I'd see if anyone had any better ideas.
Thanks

packet tracer would be fine and you could set the ip adresses so you can see it working.

you could also use microsoft visio?
