Really any one that is going to support their head, has breaks, a sun shade, storage and is comfortable and sturdy is going to be a good one. You don't need to spend hundreds of dollars to get a good one. There are plenty of pushchairs (strollers) under 100.00 that would suit your needs. just do a "google search" for strollers (pushchairs) and hit the shopping link at the top, that will give you plenty of good options.
Hope this helps!
