Per Samuel M. Goldwasser:
I did that when UPenn dropped USENET, but then someone suggested aioe
(nntp.aioe.org) which is currently free, and seems to be just about as good.
And no sign-in password.

Individual.net has been good to me for a few years now.

It's about $18 per year - close enough to free for me.
