Pragmatic answer: check the pay scales for MS vs BS. Also amortize the two years lost salary while still in school.
Emotional answer: consider the source. Slashdot responses will be evenly split. Those who have Master's will endorse it. Those who stopped at BS will poo poo it.
Fatherly Advice: make sure you like school and remember that grad school is a different world. It's more research-oriented than undergrad studies.
