MLS/MLIS

[apost]

I'm based in NY and am thinking of applying to a Library Science program for the Fall or Spring 2014 semesters.  I am debating between CUNY and Pratt and Rutgers.  Some people seem to say that an MLIS program is much more useful than a MLS program.  Do you agree?  Why?  Also, is it really worth the extra money to apply to Pratt instead of CUNY?  The difference in cost is huge.  Are job prospects really affected by whether or not the program was an MLS or MLIS?  If anyone could weigh in on this, that would be awesome.  The cost difference is huge and I need some advice.
