I currently have a Valco Buggster and a Joovy Kooper. The Buggster is my stroller and the Kooper is DHs but he doesn't use it. It's not even in his car. he lets Zoey walk, which is why he can never get anything done when he goes out with her. She won't sit in a cart with him because she knows he lets her walk. Anyway, I want to get a jogging stroller, for walking. The sidewalks are so bumpy in Levittown that's it's a pain to walk with her. Then I would just pick up a cheapo umbrella or a Volo for DH and for travel. Here's the info-Zoey is currrently 29 pounds at the ripe old age of almost 20 months. Both strollers have a max capacity of about 50 pounds. I am leaning towards keeping the Buggster because the seat is so much deeper and wider. We had it in Disney last summer and all this kids with us fit in there including my then 12 year old son!. The Kooper's seat is not as genereous. But the Buggster is a bit more cumbersome.
Here is a comparison of both

Thanks!
