O., I wish it was that simple. Everyone I know has multiple strollers. Typically the combo with the car seat for when they are infants - my advice is go light. The snap & gos can come in real handy too.
When they get older hopefully you can use the stroller, but you may find it too bulky to travel with, too small to fit them in or too bulky to store in your home. We graduated from the combination to what I call a souped up umbrella stroller from Target about $40 that was awesome - it folded up small, was light, had a basket, a tray for the kid and up top for the adult. It flew with us many places. So, I guess what I am saying is you are right not to spend too much and if you are registering - register for one of the smaller ones as well.
