Online masters degree in engineering - worth it?

I have a BS in Chemical engineering with years of experience in semiconductor industry. As a way to advance my career, I have applied and been accepted to online masters program in engineering. I will be taking same classes/exams with same grading standards as on campus students.

For those who have completed online engineering masters degrees programs, did it help you advance your career? Was it really worth it?

I am asking since I would have to pay tuition out of my own pocket (~$36k) due to downturn in semiconductor industry/sales.

Thanks in advance for your input!
