The word budget is in quotes, because there are many things that could be done differently. I decided to document the build of my lab since I did not see anything of that sort on the forum.
Components
Cisco Catalyst 2924XL-EN Switch:
This thing was listed as "Brand New" on E-Bay. I was a bit skeptical, but it came in a Cisco box and it looks flawless. Even if it is not new, at $120 (shipped), it was still a good deal!
Cisco 2513 Routers:
I bought three of these off of E-Bay, not because I felt I needed three, but because that's what the auction was for. The exterior of the routers has a good amount of wear and tear, but they function perfectly. $117 shipped for all three.
Cisco Console Cables:
Used to get into the CLI of the routers and switches. I choose to get three, since I did not want to climb behind my switch to connect the cable (I'm lazy). So I use one dedicated for the 29254. $15.97 shipped.
Ethernet Transcievers:
These transform the "AUI" port on a 2500 series router into a 10baseT ethernet port, which allows you to use a standard ethernet cable. I purchased three, one for each router. $29 shipped.
Skeletek 16U Rack:
I knew I would be expanding my lab as I moved on to the other certifications. I wanted to keep everything looking neat in my bedroom as well. I came across this rack on e-bay. The good thing is that it is expandable, and it comes in a 12U size, if you need something smaller. $124.21 Shipped.
Everything is coming along nicely. I still have to cable the power so that it looks a bit cleaner. Here is a grand total for reference:
2924XL-EN: $119.90
2 2513's: $117
3 Console cables: $15.97
3 Transcievers: $29.00
16U Rack: $124.21
-----------------------------------------
Total: $406.11 (Includes shipping)
Other things I will be getting:
- Three serial back to back cables (DCE/DTE). I found cables on E-bay that combine the DCE/DTE into one cable, and they are cheaper. These are used to simulate a WAN connection between the routers.
- 16MB DRAM. I believe this is the max for the 2500 series routers. It will allow me to run enterprise IOS.
- 2X8MB sticks of flash memory: Again, I believe this is the max for the 2500's.

Monoprice: Great place for cheap cables. Serial (DCE/DTE), Cat5/Cat6, Fiber Optic, etc!
Cisco IOS Feature Navigator: Find out what features an IOS image has. I use this to search by image name, so I know what features my equipment has.
