Using Independent Reading as an Instructional Tool

 I'm planning on having a reading unit on responding to literature in the coming month or so.  Now, I'm trying to decide what unit to follow.  I've tried a few units now including a Teacher's College reading unit and parts from our Pegasus curriculum.  

 I've gotten recommendations on two new units I'd like to maybe draw from, ideally just from one.  One is The Cafe, by the Sister's from Washington state, who are better known for The Daily Five -which I've already taught for our reading workshop structure.  The other option I'm considering is The First Twenty Days, a chapter from Fountas and Pinnell's Guiding Readers and Writers.  I'm a huge fan of both.  I'm leaning towards Fountas and Pinnell's The First Twenty Days because I can get copies of it for free, instead of buying The Cafe.

 I'd love to hear more about The Cafe!  Is it worth it?  

Thanks!
