Lightweight Stroller for 2 Year Old

I want to get a light weight stroller but wondering if it's too late to invest in one. My son still likes to use his stroller , we still use the one from his travel system. It's chicco keyfit 30 , wonderful stroller but bulky. I checked out some light weight strollers at babies R us and needed your help choosing one. I don't want to spend a LOT , but don't want to buy the cheap $25 umbrella stroller as well. I looked at chicco lightweight strollers , but most have then don't have tray and cupholders. I would love to have a tray and cupholder for my son and also for M. like the one in our regular stroller. It's always been so used. Also I would like to have good space for storage underneath. And it should be easy to close and put away. Most strollers I checked out, needs to be folded all the way down to the floor and then I have to bend and pick it up with both hands to put it in my car. The chicco keyfit stroller is not like this, it's easy to close and I need not bend and pick it up every time.
Do you know any stroller which has all the features I am looking for? I have heard a LOT abt Mclaren but none of those have cupholders? If you moms have those strollers, where do you put the the cups? Isn't that very inconvinient? I am considering Chicco lightweight (again no cup holder) or combi cosmo ( this is a new brand to M., but it does have all the features I am looking for). Also there was a graco stroller , the tray was very flimsy but the stroller itself looked good.
I need to buy it by tomorrow, help M. choose one mommas. Thanks!
