Double stroller help?

Brittany
We have a one year old and plan on getting a double stroller for when baby three gets here. My husband has his heart se on the Graco Ready 2 Grow but we would have to buy a Graco seat separately and the seats by themselves are $180-$250 from what we have found. I don't want to spend that much if I can find a different double that comes with an infant carrier for a better price.  Any ideas? Looking and the Graco Duo Glider but he keeps wanting one with a sit and stand.(even though I know my son won't use it when he is old enough for the sit and stand part)  pictures and prices would be awesome if possible.
