Now that my n00b disclaimer is out of the way

After a well-deserved break from certification studying and college classes in-between - I've decided to work on obtaining the CCNA cert - possibly to lead to a CCSP (depending on how things go. I want to get out of the strict working only on servers routine that I am stuck with at my current job.
I don't have experience with any routers and switches, as my current job only has me working with windows based servers (and anything else that nobody wants to work on - like copiers).
I'm on a tight budget and so far I've gotten the new Sybex and Cisco press books for the 640-802 exam.
Since I'm pretty strapped for cash, I wanted to see if there was any really cheap sim software or equipment that anyone would recommend for me to perform lab exercises on.
I would appreciate any help/advise.
Thanks!
