Decent CISCO routing simulation?

Is there any CISCO routing / networking topology emulation sw out there? I'd like to find something that lets me graphically "drag and drop" a few 2900's, a few 3560's, maybe a PIX or an ASA or 2 and then "log into them", configure routing, and then test connectivity and routing. Maybe using PING and TRACEROUTE to verify routes and traffic flow.

GNS3 is a router/PIX emulator that actually runs off of an IOS. So you are playing with what is loaded on an actual router. The only downside to GNS3 is it will not emulate a switch. You can even attach the router or firewall to a nic on your computer and connect it to other devices. You also must provide your own IOS image.
GNS3 supports 1700 series routers - 7200 series.
Check it out at www.gns3.net
For switch simulators you might look into Boson but their simulators dont run all features of the actual hardware.

I highly recommend GNS3 as well. Not a big fan of other sims.

You can kind of emulate a switch in GNS3 by adding a switching module to a 3600 or 3700 series "router."
Here is what features are missing http://www.gns3.net/phpBB/topic229.html and here is a write up about exactly how to set this up http://www.blindhog.net/gns3-how-to-build-a-switching-lab/
