Medical Insurance for G.C. Holders?

Hello all,
I am a Green Card holder, I have a job but it does not provide me with any Insurance. I am presently looking for an affordable Insurance (Mostly for Emergency Care)
I have seen the Fortis Insurance that Path2USA has recommended, but it is too expensive for my salary.
Can anyone suggest other Insurance's for G.C holders.

It will be a great help. thanks
