Cisco SOHO router recomendation.

I am a networking student who is interested in purchasing a Cisco SOHO router for use in a home network. I am primarily intererested in this so i can become more familiar with the IOS on my own time.

I do not need an ADSL router. My student status doesn’t give me a lot of time to work so the funds are a little tight. Any recomendations would be very helpful. Thank you.
