andymartin2006,
Welcome to the Cisco forum, you might want to read back a few posts because this has been covered in GREAT detail
For the CCNA you will need at very least 2-3 routers, the Cisco 2501, 2503 or 2514 with MAX DRAM of 16MGS and MAX FLASH of 16MGS will work and can be found on eBay for next to nothing!
You can also look at the 2610, 2611, 2620 and 2621 - these are a step up (faster) and are a little more expensive.
Google is your friend when shopping at eBay - if you do not know what a Cisco 2521 router is - GOOGLE it and you will find all you want to know. You will also find that you are learning about Cisco products also.
Check eBay - several sellers have complete kits with max DRAM and FLASH, transceivers, seial cables etc. as well as latest IOS with a backup on a CD - these can be a little more but saves in shipping with a 1 stop buy! Just watch the ones that keep pushing the CAT 1900 switches for CCNA - you need the 2900s
Do a little shopping around and you can get some great deals. Just make sure you understand which are Token Ring routers (2502 and 2504 to name at least 2)
If you can not get everything - then check
- he has all the extras you would need like FLASH, DRAM, serial cables, rack ears, transceivers etc. I have bought from him several times and price was always good and parts always worked fine.
Hope this helps!
