jsaucie,
First - start checking out the routers and switches on eBay - take your time and "Google" stuff you do not understand - if you do not know what a Cisco 2501 is then "Google" Cisco 2501 and LEARN
One of the BEST books as well as one of the only books I have EVER seen about setting up a home lab - Cisco Press CCNA Practical Studies by Gary Heap CCIE ISBN - 1-58720-046-5 - this is for the old CCNA exam 640-607 but it walks you through setting up a 8 router lab with 2500 routers - it covers getting the routers, configs, and even setting up a 2511 for reverse telnet so that you can console into any of the 8 routers. For about $16 used - GREAT Book !!!
For CCNA you really only need 3-4 routers and 2 switches but this will be the base for your CCNP lab - DO NOT TRY TO DO IT IN ONE FELL SWOOP!!!! Take your time and pick the best pieces - if you are lucky and find several together then you might save some shipping but lots of the kits add some really old junk at times.
Try to get 2 Cisco 2501/2503/2514 routers with 16 mgs DRAM and 16 mgs FLASH - that is the max for those routers, you also want the latest IOS you can find on at least 1 since Cisco DOES NOT give the IOS away for FREE!
Look at a Cisco 2520/2521/2522/2523 for your Frame Relay switch/router - they have many built in serial connections to connect several routers in a FR setup. Does not matter that the 2520 or 2522 are Token Ring - (might be cheaper) since this will be your FR switch.
You should look at a Cisco 2620 or 2621 for the fast ethernet conections so that you can do the switching and vlan labs, you will also need a WIC WAN module so that ytou can connect to the 2500s.
Switches - 2950 - not cheap, try to start with 1 and watch for another. You can make do with other Cisco switches as a place to plug in your Ethernet connects - but you will want a 2950 with the Cisco IOS on it so that you can do what the CCNA will question you on.
Once you have the routers, if you need DRAM, FLASH, cables, "ears" etc. check out -
I have bought from him 3 or 4 times - he is in Hong Kong
At a Cisco Networkers convention all the CCIEs and CCNPs kept talking about getting parts from Anthony Panda
If you have questions about your Cisco equipment - GREAT FAQ here -
Some good points here on a CCNA home lab -
Hope this helps!
