Teacher Cert. & MEd - Opinions?

[DSTRen13]

I am trying to go back to school to get certification to teach (currently I'm looking at high school English; I would prefer history but apparently there is a much larger job market for English teachers here). I have a B.S. degree, and am looking into different option on getting certifications, and many people have recommended going ahead and getting an MEd at the same time as I work on my certification.

I eventually want to go back to school (yes, back to school yet again - I like school), for an MA and a PhD, looking at issues in the American education system, so I'm looking at my high school teaching career as sort of a 5+ year field study. (Hey, maybe I'll fall in love with it and never leave, who knows, but I have always really wanted to pursue the PhD - it is my dream!)

So, the point of all this explanation ... in your opinions, is it worth it to get the MEd? If it would really be beneficial, I am totally fine eating nothing but rice to pay for it (it would be a good diet!), but I am not convinced it would be a good move for me if I am not planning on being a career teacher.
