Well, since no one has answered, I'll share my two cents.  Note: I'm not in C&T; my department is significantly smaller than yours.  Professors have taught all but two of my classes (the guy who taught those two classes is now a full-time instructor--he was finishing his dissertation when he taught us last year).  
TC is very expensive and can be stingy with financial aid.  Personally, I'd have a hard time paying that kind of money for fellow grad students to teach me.  This may be secondary, but one concern I'd have would be recommendations after graduation.  I suppose all of your recs would come from grad students and not established professors??  
One thing you should do is email the masters advisor and ask him/her to get you in contact with a couple of MA candidates.  Talk to them about their experiences.  That's what I did prior to entry; the tips I got were invaluable.
ETA: Just as an FYI, C&T didn't always rely on grad students to teach (I'm shocked to hear that's common now).  When my mom was a student there, she only had professors.     

Hi wtfook, do you have any information about the Teaching, Learning and Leadership Masters program? Have to decide between this and Curriculum and Teaching at Teachers College, and it's quite the dilemma. One big critique that's consistently leveled against TC is that some classes will be taught by TAs, and was wondering if Penn GSE has the same issue. Any other info on how American-centric the program is (both in terms of student composition and focus of the courses as I'm an international), access to professors outside class, details of the compulsory internship etc. will be really appreciated!
