The Chicco KeyFit seems like a great infant car seat, but I'm not finding many options for a compatible stroller frame. From the research that I've done, it seems as though the KeyFit is only compatible with Chicco's own Ct 0.1 stroller or as a part of their Cortina Travel System. Both of these seem to be large, heavy options...although apparently very well designed. (Maybe someone will convince me that these strollers are the way to go...)

Baby Bargains gives good marks to Chicco's own C5 lightweight stroller, but I don't think it can accomodate an infant car seat/carrier.

Has anyone found a compatible lightweight stroller/frame for the KeyFit? If not, we may choose a Graco SafeSeat or SnugRide because the Gracos appear to be compatible with a greater variety of lightweight strollers/frames.

I'd appreciate hearing back with any thoughts, experiences, pros/cons, etc. Thanks in advance!
