I have a Kolcraft Contours. We tried it a couple of times before the baby came along and both my 2 and 3 (at the time) year old loved it. The baby likes it too, and it has an attachment for our baby carrier that fits perfectly. I like it for a few reasons: I can fit 2 kids and don't have to be chasing after my 2 year old while tryng to hold baby, The seats can be both facing me, both facing front, facing eachother, or one face me, and one face front (thats what I use with baby). also both seats recline which is a nice feature with a newborn, as well as a child who still naps and ocassionally falls asleep. There are also disadvantages: it takes up alot of room (even in a minivan trunk), it is heavy (but I can lift it myself), and we have to take the front seat off in order to fold it up (which can get tiresome). However, for me the positives outweight the negatives.
Also, I just wanted to add that a good place to look for double strollers is Burlington Coat Factory's Baby Depot. That's where we found the cheapest price for ours. (I think around $199?) They have a wide variety, so they might have one there you like for a decent price!
