I can perhaps offer some advice. I have a tier-1 technical undergrad and a MSFE in a tier-2 college near NYC (cost was a major factor - 3x cheaper?!). While the academics covered in MSFE in the tier-2 college was probably equivalent to the academics in a tier-1 college, the quality of the networking and career placements is dependent on the school. My tier-2 college placed well only for the NYC area for boutiques, diversified financial firms, and asset management firms and not so much on the widely known investment, bulge banks.
Upon graduation, while I received offers from my local's career placement services, I leveraged my network from my tier-1 undergrad to secure a sweet job in a top firm halfway across the country in a major city. I'm now looking at a tier-1 MBA for a career switch (sort of).
I would definitely research your schools' employment reports and talk with professors as well as alums to see what your career prospects are before committing to a school. Then you can figure out if the school is the right fit for you based on the data from the employment reports. If Bentley places well in Boston or has a significant number of alumni there, then it might be a good fit for you. Just my two cents.
