I mentioned in another thread I'm reading "Deploying and Troubleshooting Cisco Wireless LAN Controllers" . It seems everyone wants job experience with Cisco (although I don't know why when UBNT has such disruptive pricing). I don't have a WLC to play with so I went searching for a network simulator and came across this:
http://networksims.com/

Anybody use them? Opinions? It's cheap enough for me to go ahead and get so I may do a review on it later but they cover a BUNCH of emulators and it seems like it would be a valuable resource for people taking exams.

I got time to mess with it for a little while this afternoon and so far it's pretty awesome. I got the $58 bundle (one year) and it includes this:

• Router, switch, PIX/ASA, Wireless, ASDM, VPN and SDM simulators.
• Google book integration.
• Cisco command/term/concept search.
• CCNA.
• CCNA ICND,CCNP SWITCH,CCNP ROUTE,CCNP TSHOOT.
• CCNP: CCNP1 (Adv Routing - BCSI).
• CCNP2 (Remote Access).
• CCNP3 (BCMSN).
• CCNP4 (Debug).
• CCNP5 (ISCW).
• CCNP6 (ONT).
• CCNP Security SECURE (New!).
• Wireless.
• SNPA (PIX/ASA).
• Security.
• Host (Windows/UNIX).

• CCVP (Voice Gateway).
• CCNA Wireless (with new WLC and ADU).
• CCNA Security.
• CCSP (SNRS).
• CCNA Voice.
• ASDM.
• SDM (Alpha release).

• Microsoft .NET.
• Series of integrated lectures on security, wireless and switching.
• Fun activities.
• Full range of in-package and on-line tests.
• 70,000 test questions.

AND a bunch of books. There were 6 or 7 just on CCNA.
It has you go through a series of challenges where you have to type in the correct commands on the different emulators to complete the task. This is mixed in with test questions and videos. For such a tiny price, it's really awesome. I haven't even got to the Ethical Hacking section yet I was so busy playing the Cisco WLC stuff.

There's a demo you can download on the site to try it out and some videos about the different demos http://networksims.com/emulators_demo2.html

It has different topologies you can use as well (different routers, switches, number of hosts, etc).
The only bad thing I can see so far is you can only use it on one computer.

I'll post more when I get a chance to really look over everything...it's got months worth of reading.

It looks like the premium package ($78) lists e-books, but you said you gets lots of books with $58 package.  Trying to figure out what benefit the extra $20 is other than a suite of tools (don't need them anyway).  Looks like a good deal and it is hard not to get $60-$80 value.

I went ahead and got the $78 package because it indicated that updates would be provided for the first year, whereas the lesser packages required a $30/quarter subscription service for updates to the materials.  I missed that the first time through.  Now, whether or not the updates (or the toolset) is really worth $20, time will tell.  Thanks for pointing out the site, now I just need more time to look at it.
