This info was in Sunday's paper. I have not checked out any of the sites yet, but plan to (comments are directly from the Tribune). Truth be told, writing this post is a way for me to get another piece of paper off my desk while having a record in case I find stuff in the future to ditch. Wish I knew about these sources before I donated a TON of electronics to Goodwill last month...
