MS OR MBA after BE .....?

-I just finished my BE in elec n telecom with 70+aggregate

i am confused regarding my future.

should i study for GRE and do MS next yr OR work for couple of yrs in whtever job i get n do MBA from a reputed coll.

i think i can manage either.....but doing MS means taking a loan of 30-40lac now which is a risk....

MBA in India would mean a loan of say upto 10 lac n US would be more again

i wanted to know wht has better scope in terms of good job and pay
