For the first six months, we used the Snap & Go frame. It was really convenient, big basket, let us put off making a real decision, etc. We registered for one and got it as a gift, but if I were buying it myself I'd definitely just buy used.
After extensive research, we now have the Baby Trend Expedition (which I use for jogging, but I'm slow... currently doing Couch to 5k so not exactly pushing it at high speeds!!), the First Years Ignite and the Baby Jogger City Micro. I wanted one umbrella stroller for each vehicle (we use each with equal frequency and don't want to be caught strollerless, which happened a few times when we were sharing the Snap & Go).... planned to get two Ignites, but found the City Micro on Target clearance for $50 and couldn't pass it up :)
Anyway, I love our jogger but I can't imagine using it for everyday use. A coworker uses it as her everyday stroller and loves it, but to me it's too heavy/bulky/etc to be getting in and out of the trunk with every errand. I also don't like the fact that it can't be folded/unfolded one-handed. I'd suggest getting two separate strollers. The Baby Trend Expedition is only around $100 and the Ignite is around $50, so you're still spending less than most people spend on just one stroller :)
