Try Podthoughts by Colin Marshall. It doesn't always work for me, but he does go in depth and give a solid listen and consideration to the podcasts he reviews. Find it at: http://maximumfun.org/tags/podthoughts
If I think of others, I'll let you know.
And speaking of word of mouth, what are you listening to that you really like?
