InStep Safari is very decent and not very expensive.
I have heard a Bob is nice, though that's top of the line for money.
Just make sure you get a swivel wheel. Getting a fixed wheel is impossible to turn. Many strollers have both options. I say this because we have bought fixed wheel joggers before (they say they are the only kind to use for real running), but I found I could not turn them at all. A total waste.
Babies should be 6 months before they use a jogger if the parent is actually jogging, note.
