Then my wife bought a BOB at REI. It was ridiculously expensive (>$350 IIRC), but the per mile cost is much better than the old piece of junk. It is completely effortless to push or turn, which reduces the excuses for going out on a jog. It's very comfortable for the baby/toddler, so less crying/whining to get out.

After 6 kids, I would guess we've owned close to 12 strollers and this one is by far my favorite.
