Question : Network Topology Simulator

I once again come to the experts for sage wisdom.

Here is my current dilemma.  I am in the process of getting my Network+ certification.  I have a strong computer science background, but my networking knowledge is limited.  What I am looking for is a network topology simulator that will allow me to create a virtual network composed of routers, switches etc.  The perfect solution would then allow me to change the configurations on these items and the effects would be displayed.  Again in my utopian world the configuration would be modeled after actual products, ie I could put in a Cisco PIX firewall and the configuration dialog would resemble what I would see in the real world.

I'm looking for something that will help me learn without having to buy $50K worth of equipment.

Thanks!
