I ended up going with feedburner.com

I did this because it will be the best for our site users. If I change the site design I simply need to change the link at feedburner. All the sites and users that link to by podcast don't have to change anything.

The one problem is that all the links to my mp3's are through feedburner so I use the direct links back to my site on all those pages. I think that is worth the ease of use for me and our users.

Thanks,
JC
