The Cisco Dual 3640/2520 Router kit is a modular kit that supports all the features to pass your CCNA test. As you may know, the new CCNP test requires IOS 12.4 which the cheaper routers do not support so you will need to step up to the 3640 series. The new CCNA exam also requires IPv6 and SDM knowledge and this kit supports both. Other kits don't have console kits, serial cards, back to back cables or the latest IOS software.  No one else has our copyrighted 224 page CiscoKits Self Study CCNA Lab Workbook(see the lab topics by clicking the link) that will walk you through 60 different labs! Why spend hundreds of dollars on a lab kit if you don't have the labs to accompany your equipment? You will also get our CiscoKits CCNA/CCNP Test Engine with over 500 different questions. Not only that, but you will also get CCNA test tips, the IOS on CD, Cisco's TFTP Server and other prep material.  There is also more!  You will also receive our CiscoKits CCNA CRAM Sheet.  This six page, full color, laminated foldout is a great addition to your CCNA Study arsenal.  These routers are in excellent condition and are guaranteed working! The extra information provided on CD is worth $200 by itself. You will be provided with everything you need to hit the ground running to prepare for your test. No need to spend hours looking for tools, procedures, test review material or fumbling around looking for labs. This is a great educational lab kit. Software licensing is the responsibility of the buyer and is provided on the CD only as a backup of what was loaded on the router when we purchased it.
