iTunes pod-cast download question.

I have "subscribed" to a pod-cast on iTunes and if all goes well with transferring the pod-casts to my MP3 player after downloading to my computer, all is well.

But there are times I would like to delete the pod-casts from my computer and go back to iTunes and do a fresh download of the pod-cast that I previously downloaded to my computer.

How do I do that? On iTunes there is no longer a "Get" beside the individual pod-casts I would like to re-download.
