I've just begun studying for my CCNA and I can't afford to buy an old Cisco router right now. However, I do have a Pentium II that I'm not doing anything with. Is it possible to install IOS on a pc so I'll have a pseudo-router to practice on? If not, does anyone know a good place to get something like a used 2500 _dirtcheap_? I looked on Ebay briefly but the cheapest one I saw was like $200.

Thanks a 11110100001001000000 for any help!
