The Bugaboo Donkey is amazing I have heard! And.. for having a Bugaboo product.. their Bugaboo Bee... I would put money on it that that stroller is amazing too! They are VERY well made strollers, practical, functional, light weight and the drive on them, I know that sounds silly, the way they ride/drive is amazingggg... so fluid!
I have also heard that the "city mini" is the bees knees when it comes to double strollers! :)
