I looked at all the joggers, read a ton of reviews, and ended up with the Dreamer Design jogger. Less $ than a Bob, but I liked some of the features better. It's got a great sun canopy, the newer models have a super easy to use harness, and it's really easy to run with/steer. I use it mostly for 3 mile runs, and you can get an insert to accomodate a newborn. Great jogger. However, if you're going for shorter runs and want to cut down on # of strollers (we have 3), I have a friend who has the Zooper Boogie that she uses for walking/errands/running and she loves it for all purposes. I prefer the larger, 16" wheels, for running, but the Zooper seems to hold up and her daughter has a totally smooth ride when we run together.
I also have the Maclaren Triumph for our lightweight, umbrella and think it's great for babies 6+ mos. Small and lightweight for traveling or keeping in your trunk. Airport travel is super easy with it.
I'm not sure about other strollers, but I know with the Pliko you can get adaptors to snap your carseat into the stroller, so if you went with that option (and I know there are others out there, just not sure which ones), you could elminiate the snap 'n go which is only good when you have an infant seat.
