We had a jogging stroller in Japan (made by a Japanese brand) that we left there. Stupid mistake. When we got here I really wished I had brought it.
I did lots of research, but didn't want to spend too much either. I read tons of reviews and stopped a couple of people to ask them how they liked theirs.
I finally bought the InStep Safari. I love it! I bought it on ebay through a company called VMInnovations. It is listed now for $119.00 with free shipping. It came with a kid's tray and a carseat adapter that you can snap on. I didn't think I would would use the carseat adapter, but that has been great! It also comes with a mosquito net. It has a decent basket underneath and a nice pocket on the back of the seat (where I keep the mosquito net). It also has a parent tray.
It steers easily and has a head cushion and padded covers for the shoulder harness. It folds and unfolds really easily. The only thing I have found is that the front wheel got a bit loose on mine, so it wobbled. All I had to do was take off the black cover and tighten it just a bit. No big deal.
I love it and would highly recommend it.
As far as double strollers go, I have a PegPerego one that I bought off of craigslist. It's okay. The wheels don't turn as easily, which is one reason I really wanted a jogging stroller. I debated about whether or not to get a single jogging stroller or a double and decided on a single for a few reasons. A double is a lot bulkier and would not fit in the car as well. It is much wider. I feel that the cheaper ones with just one wheel in the front are not quite as stable as the more expensive ones that have four wheels.
I have 3 kids ages 5, 2 1/2, and 5 months. I have an Ergobaby carrier for my baby. What I usually do if we're out for the day is the 5-year-old walks the whole time. The 2 1/2 year old starts out walking. If she is very tired towards the end, I will put the baby in the Ergobaby carrier and let her ride in the stroller. Oftentimes, she will also sit on the black front wheel cover, facing backwards and holding onto the kid's tray.
