I love my BOB Duallie. It has large, separate canopies, reclines nicely and pushes like a dream. It's big, but it handles well. It's a bit on the spendy side, but they go on sales twice a year at REI or you could sign up to be a member there and get a 20% coupon. It's worth the money for sure! It took a lot to convince my husband that we should spend that much on a stroller. The fact that we bought it 20% off brand new at REI and it was about the same price as people were selling them used for on eBay and craigslist was a great selling point to him. Now that we have it, he LOVES it. He's like the BOB spokesman when we are out in public with it. We also just took it to Disney World. It's a little bulky and hard to handle through the airport and on the busses at Disney but we can't imagine what it would have been like without it. I could go on and on.....I just love it. I was able to push it through a food court with one hand with my kids in it while carrying a tray of food with no problem. There are a lot of nice, smaller double strollers out there, but none that push as easy as this one.
I think if I had to pick one thing about it that could be improved, it would be that it would lock in the folded position. We just used a bungie cord around it for traveling.
Good luck!
BTW, I have a 3.5 yo and a 20 mo old.
