C.O.
My GF has it and hasn't really complained about it. We don't have it personally so I can't comment.
My GF has said that it's more like an HMO than a PPO and equals it to Kaiser...and I never really had a problem with Kaiser...only reason we switched from Kaiser was because at the time the nearest hospital was 1.5 miles away and Kaiser was not accepted there and the Kaiser doctors didn't have privileges there...
Would you like me to call her for more specifics? She's here in VA with me so I don't know if it's different in IL...
