Router for play @ home

[Mike Sholar]

Hello people!   Not exactly a cert question, but it applies. I will soon be getting cable intenet access at the house, and would like to purchase a cisco router to play with behind the cable modem. What series router should I be looking at, just to learn the ios and play around with. I am working on my CCNA, and realize a physical router is not necessary, but I will be progressing upwards and would like the experience. I looked at the 924 cable modem/router cisco sells, and the $899 price tag was a little much for play-time! Thanks for the input.   Mike   MCSE, MCP+I
