mac mini audio input?

[John Heim]

I was just about to take the plunge into the world of the macintosh via a 
Mac mini. But I've been told it does not have an audio line-in jack, just a 
line-out for headphones. Is that correct? i want to connect my stereo to my 
Mac so I can record radio programs.  Is there a cheap and easy way to do 
that with a Mac mini?

I figured that the Mac mini would be the ideal device to record radio 
programs because it's low-power so I could leave it on all the time. Plus, 
it would be nice to be able to listen to the programs on the same device 
where they're recorded. Right now, I have to transfer them to another 
computer.
