I have 2, I have a Maclaren stroller that I love love love but obviously is only one child at a time! If I was having another baby I would sell mine and get one that lays back and would just use that from birth. Twas about $250 on sale.
I also have a P & T sport - about $600 with a double kit but I think they are cheaper now. I love it and use it a few times a week for walking with the kids. I know some people don't like them as the child underneath can't see much but my kids love it and they are 4 and nearly 3 - it's a cracking work out too!
We bought the Baby Jogger City Mini double and it seems great so far! We got it for $500 but on sale and with no box or anything but I was fine with this because it was black. I'm super impressed with how easily it folds, it's actually easier than my single pram. One of my girlfriends commented on how great the turning circle was as well. My only disappointment? I bought gorgeous seat covers and they get in the way of the handle which you need to pull to fold so the seat covers end up all squashed when it's in the folded position. Seriously no biggie. DH was dead set against any front/back prams as he thinks the underneath child gets absolutely no view. I tried the City Select but it felt too long for my liking. DH really wanted a side by side and as it fits through doorways, I'm happy too.
