Info gathering: Excellent intro undergrad lab courses and facilities?

Introductory undergraduate labs are a recurring challenge at nearly every university.  Is the purpose to teach students something about how experimental science works (formulating hypotheses, defining measurement needs, setting up equipment, acquiring and analyzing data)?  Is the purpose to emphasize and reinforce specific scientific points from the curriculum?  How structured should they be?  Where are there opportunities for interdisciplinary labs rather than traditional physics/chemistry/biology/earth sciences stovepipes?  

I'm interested in learning about US examples of outstanding introductory physics labs - both in their content/execution, and in the intro lab facilities that my readers consider to be particularly well done.  Please respond in the comments or via email.   I'd really appreciate your thoughts on this, even knowing that my blog readership is a highly biased sample.

(I tried launching a survey about undergrad physics lab instruction five years ago.  I got zero responses.  Hopefully this will be a little more successful.)
