if you really jog, you're best bet is finding a gently used BOB or Baby Jogger on Craigslist. A friend found one for about $150... couple of years old, but smoother ride than a new baby trend. the new baby trend is around $200. It is crap. I tried a new one out in store... flimsy. I had a single baby trend expedition that I loved... but the double was aweful. I don't jog ... just walk long walks with the kids and a dog. I use a Phil & Ted sport with doubles seat. my kids love it, I can push it one handed. and I use it in mall and for every day. I did jog a 5K with it... but I don't think you're supposed to. If you're a jogger.. go for a great brand used. most hold up really well.
If you really want it for running, I highly recommend the Baby Jogger Performance series. I already have the double of this and use it for just DS #1 (I got an amazing deal on a used one). It is pretty expensive new, so CL or consignment is the way to go. If you find one, snatch it up.
