Ok, I just read this on Harvard's page: "The figures below are the costs of attendance for the 2011-2012 academic year at Harvard Kennedy School." A total of $86,000+ over 2 years is unbelievable.
I agree that plenty of people in the MPA field do have knowledge of and respect for Maxwell's program, and I've heard from alumni directly that the alum network is super strong they take care of their own very well in helping people get good jobs afterward. I know the 12-month program means you can't work part-time during the year or get a summer internship, but personally I would rather save the $36k and get back into a full-time working position after 1 year instead of 2.
Getting back to the topic of Harvard's program vs. Syracuse though, I've heard that Harvard has a more theoretical focus (and appears to have minimal proscriptive coursework, so it may be more flexible), and Maxwell is more practical and focused on building applicable skills. Could just depend on what you really want out of your degree.
