I have two:
Double Snap-n-Go - It's fine for quick trips to grocery, Target or doctor appointments. We've taken it on walks and quite frankly, it's not the best on sidewalks or uneven pavement. Small wheels. Does have a huge storage basket, but you can't easily get things in and out. It'll serve it's purpose and be worth the $80 we paid for it. I also don't care for front to back type layout, it's impossible to maneuver in tight spots.
Valco Tri-Mode Twin - Just got this last week and it is one fabulous stroller!! Very well made, pushes like a dream (even one handed), has tons of thoughtful features. I love it! We have the optional toddler seat attachment, best idea ever. DD (3.5) loves it. It fits through standard doorways and maneuvers very well. It can double as a jogger (probably not heavy duty jogging) as the wells lock. The only downside is that you can only attach one infant carrier at a time, and that is a separate purchase.
